Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.

LED Backup Light for Truck or Trailer - Submersible - 10 Diodes - Oval - Clear Lens - Qty 1 - BUL10CB

Average Customer Rating:  4.6 out of 5 stars   (40 Customer Reviews)

6-7/16" Oval. Waterproof trailer light is certified for backup light function in a 2-lamp system when a pair of lights is installed. Recessed mount with grommet (sold separately). Accepts 2-prong plug. 10 White LEDs. Clear lens.

by:

I purchased these Submersible LED bulbs for my boat trailer for two reasons. The first is so road traffic is aware of my intentions of backing up and the second is to make it easier to back my trailer into my driveway at night. The only thing that I find disappointing about this product, is that the wires are not sealed. You have to plug a pigtail in to power the bulb. Although they say it is watertight, I still plan on sealing the plug with some marine grade silicone sealant. Otherwise I am very satisfied with the way these bulbs light up my path of travel.




by:

Nice lights. I have the 36 diode oval LED lights mounted on a flatbed truck as reverse lights and they are not near as bright as these 10 diode lights. I have the 10 diode lights mounted inside a 6ftx20ft stock trailer on a toggle switch. There is one at the front and one at the back. They give off plenty of light to load and unload horses and cattle in the dark. I would buy these again for the next trailer I rebuild. The team at etrailer.com is top notch as well. Your order will ship the same day and arrive in a timely manner. If it does not they will tell you why. Great people to do business with.




by:

Product exactly as needed. Existing lamps last about 8 to 10 weeks as docking lights on my motorhome; there are four - one at each wheel. These lamps fit perfectly and are much brighter. My expectation is that these lamps will last more than a year(?) We'll see.


Comments
So far these lights have exceeded my every expectation! Absolutely no problems whatsoever. Thank you for making a quality product that I can depend on

What I needed for light replacements




by:

the light fixture works very good except when used in the bracket, it leaves the back exposed to being hit by road debris. There is no cover on the light fixture. Therefore i went to a local fabricator and he made a fixture out of 2x4 steel tubing. The gasket fit perfectly but when i went to us the 2 wire pigtail, it was at the wrong angle for the light. I purchased another one locally. just wanted you to know that i could only use the light and the gasket.

Thank you for your prompt service.




by:

Great and perfect replacement for the backup lights in my headache rack.




by:

Very bright look great direct fit plug n play




by:

Fit like a glove!




by:

I can't believe the difference in the looks of my Damon Outlaw Toy Hauler after adding the new LED taillights, not to mention how much safer it will be with the added visibility. The rear of the coach looks brand new with the old faded lights removed and replaced with your lights. Everything was just plug and play. Well worth the cost. Thanks, Michael


Comments
I get compliments on the way the motorhome looks all the time. The transformation was really worthwhile, and the back of the coach is MUCH MORE visible poor weather than it used to be. I am completely satisfied!

Gets off good light and is very durable




by:

The lights are great, however, you should probably sell as a kit to include the mounting brackets and wiring harness. I had to make a second order to complete the installation on my truck.




by:

Installed as an interior light in my horse trailer. Works great, although it was slightly bigger than the previous light and was a bit difficult to install. High output with very little power draw. Just plug in, no electrical work. Received very quickly.




by:

Etrailer.com is my "Go To" site for trailer lighting and parts. Always reasonable prices.




by:

etrailer.com had everything I needed to complete my trailer build, and at the right prices. The products are quality, with competitive pricing. etrailer.com delivered as promised, it was our local delivery that delayed sending the product out to my home, but one call to Pat, and the issue was immediately resolved, and I had the product that night! Great product, Great customer service!




by:

I ordered LED trailer running lights - were very easy to put in - not quite as bright as I would have liked, but did may a noticeable difference.




by:

Product worked fine. Only took a couple of minutes to replace my old trailer lights. Lights are much brighter than my old bulb type lights.




by:

Finding and purchasing products from etrailer.com has always been easy. I have purchased many times from etrailer.com.
Parts arrive on time and never had a problem.
Good job.

Comments
Thank you for the reply.You are correct the light has a three prong socket on the back but this light only uses one function. You need a ground connection and the reverse signal connection. The 2 prong plug I recommended will actually cover up that third slot so you dont have to worry about it getting dirty or damaged.

by:

Product looks great, just wish I had known it needs a wire harness instead of just having the wires already installed.




by:

Huge difference in brightness from these back up lights compared to those which came on my Ranch Hand Legend rear bumper. Product was as described and arrived sooner then I expected.




by:

Was just what I was looking for. They had the red lights at our local store but I couldn't find the back-up lights so I went on line and found e-trailer. Realized I could have gotten everything from them and will keep them on my fav list.




by:

These provide a lot more light than the bulb type lights. Connections on the back match what was on the trailer. I replaced the rubber grommets at the same time as they are not very expensive.




by:

Product well made and was as advertised. Led lights will be used in my Ranch Hand bumper.
Easy to install. I already have the mounting base and wiring.




by:

I made this purchase for my son's boat trailer. I ordered on the Monday before Thanksgiving and it arrived the day before. Everything arrived as expected and well packed. He can't wait to get this installed!




by:

Delivery was quicker than expected. The answer to the review by the staff was extremely helpful in deciding which light would work for my intended use. Have bookmarked etrailer for all future purchasing.

  • Difference in Brightness Between # BUL10CB Backup Light and # BUL72CB Utility Light
    Both the # BUL10CB and the # BUL72CB are 10 diode lamps, and therefore neither lamp would really be brighter than the other. The main difference between the two is how the light is focused. Because the # BUL10CB lamp is DOT compliant as a back-up light, the light would be more diffused over a wider area. By contrast, the # BUL72CB which is NOT certified as a back up light would have the light more focused on a smaller area. Each lamp would output a similar amount of light, but the # BUL72CB...

  • LED Backup Light Recommendation for a 2015 Ford F-150
    Your 2015 Ford F-150 should have a 7-way trailer connector at the rear of it. The wire running to the center pin is the reverse light circuit and would be the wire to use for adding a reverse light. The part # BUL10CB would work as a back up light but it is a recessed mount light that would require cutting a hole in your trailer. For a grommet you would need # a70gb and a pigtail harness # A47PB. You might prefer a surface mounted light like the part # BUL90CB since it can be attached...

  • What are the Brightest 6.5" Oval Lights for my Motorhome
    Because the GloLight LED Backup Light for Truck or Trailer part # BUL111CB slightly diffuses the light around the outside of the light I recommend using the LED Backup Light for Truck or Trailer part # BUL10CB. This will give you a slightly brighter light than the other. To be honest the difference is minimal and I like the looks of the GloLight better but for maximin brightness the second option is the better of the two.

  • Output of the Optronics 6-1/2 inch Oval Trailer Lights
    Optronics uses candelas to rate the brightness of their lights instead of lumens and the output of the Optronics 6-1/2 inch Oval LED Back Up light, # BUL52CB, is 175 candela. At a distance of 1 foot, the candela output is equal to the output in lumens. The next brightest 6-1/2 inch oval light would be the part # BUL22CB which has an output of 160 candela. The part # BUL10CB that you referenced has a candela rating of 125 which would make it the dimmest offering which I would not recommend...

  • Reverse Light Recommendations and Difference Between 2 and 3 Wire Pig Tails
    The LED Backup Light # BUL10CB with 10 diodes will fit in the Rubber Grommet # a70gb. Also, the Sealed, 6-1/2 inch Oval LED Trailer Back Up Light # BUL52CB with 36 diodes will fit in the # A70GB. 7/16 of an inch is pretty close to half an inch and honestly it was probably a measuring error as both lights will fit yet they are listed as having different diameters. The 36 diode light will be noticeably brighter than the 10 diode light. It really just depends on how bright of a back up light...

  • Why Would LED Trailer Light Stop Working
    The lifespan of LEDs are typically much longer than what they would ever be needed for. They don't burn out like traditional bulbs which is one of the many advantages to them. Most likely your issue is ground related. Try improving the ground on the right turn signal and you should get the light to work again.

  • Recommended Optronics Assembly for Adding Backup Lights to Sprinter
    I recommend going with the Optronics LED Backup Light # BUL10CB, as it will provide you with a clear, bright LED and it is DOT approved to be used as a backup lamp. The Optronics Sealed Oval LED Light # BUL78CB that you also mentioned is a nice utility light, but it is not actually DOT approved to be used as a backup lamp on a vehicle. To install the light assemblies, you can use the 2-Wire Pigtail # A45CB. The white wire will be attached to a bare metal surface of the frame for ground,...

  • Installing # BUL10CB LED Back Up Lights on Pontoon Boat Trailer
    Four of the LED Back Up Lights, # BUL10CB would only pull about 1 amp, which is less than two incandescent lamps would pull and should not cause a problem. Typically, a pontoon trailer would use a 7-way trailer connector. Check the center pin on the 7-way connector on the tow vehicle with a circuit tester to see if it shows voltage when the transmission is shifted into reverse. If so, simply wire the reverse lamps to the center pin on the connector on the trailer. Then, when the vehicle...

  • Light Output of Optronics LED Utility Light # BUL78CB Versus Standard # 1156 Bulb
    The light output delivered by the Optronics # BUL78CB would be considerably greater than that of a single 1156 single filament bulb. A single 1156 would put out about 32 Candela, while the Optronics # BUL78CB puts out 125 Candela. If you were considering using the # BUL78CB as a back-up lamp, keep in mind that it does not meet DOT specifications as a back-up lamp. This will not present a problem unless your trailer is used commercially. If you need to meet DOT specs, use a lamp like #...

  • Can Reverse Light of RV Be Used as Utility Light
    Sounds like you want utility lights at the rear of your RV instead of a reverse light since you mentioned you didn't want the lights to come on when in reverse. So what you could do is run the power for the lights from the RV battery and then use a switch like the Derale part # D16740.

  • Comparing Brightness Ratings of Optronics LED Tail Lights
    The Optronics LED Backup Light # BUL22CB is brighter than backup light # BUL10CB although I would not describe it as significant, though that can be subjective. Optronics measures the brightness of their lights using candelas and the # BUL10CB has a candela rating of 125, while the # BUL22CB has a candela rating of 160. There is also the backup light # BUL52CB which has a candela rating of 175. The reason I would not classify the brightness as significantly higher is because these lights...

  • Is the Custer 4 LED Strobe Light part # STRL4W Waterproof
    In order for something to be considered waterproof it needs to be able to withstand submersion for a certain amount of time without any water leaking in. The Custer 4-LED Strobe Light or Running Light # STRL4W would work well on the exterior of your vehicle and normal amounts of rain wouldn't break it. But I would not recommend it for a boat trailer where the trailer gets submerged. For something like that you would want a LED Backup Light part # BUL10CB.

  • Can Reverse Light Circuit of Trailer 7-Way be Used to Power Additional Reverse Lights
    If the reverse light circuit of your 7-way is active you can use it to power the reverse lights you bought. It would be a matter of running the power wire of the light to the reverse light circuit of the 7-way and the negative to the ground circuit of it. If the circuit isn't active on your trailer wiring you'd then need to tap into the reverse lights of the truck. For a quick splice connector you could use the # SWC502905-1 to make the connection to the circuits.

  • What is the Candela Output of Optronics 6-1/2 Inch Incandescent and LED Tail Lights?
    I do recommend you move to LED lights as they are going to last much longer than the incandescent lights on your horse trailer. As far as light output, Optronics generally measures their lights in candelas instead of lumens though at a distance of 1 foot candela is equal to lumens so you should have a good idea of how bright the lights are. I contacted Optronics and the representative was able to give me the candelas of each of the lights you were asking about. The incandescent # BU70CB...

  • DOT Approved Trailer LED Reverse Light and an LED Interior Trailer Light
    Optronics light # BUL78CB is a utility light so it is not DOT approved to be used as anything other than that. For the interior of the trailer it will work fine, it doesn't have to be DOT approved since it isn't a tail, marker, reverse, brake, or turn signal light. It is about as tough as any other trailer light that you would find but I would not expose it to repeated impact from cargo. the lens or flange would eventually crack. If you are looking for a DOT approved reverse light with...

  • How To Connect Electric Trailer Brake Assemblies To Junction Box On Trailer
    You have a good plan! You are correct that once you have a functional 7-way connector and the Tekonsha Prodigy P3 # 90195 installed in your truck that you will not need any other wiring on the truck. Going with a junction box like the # 38656 to install the 7-way connector is the best way as it gives you a very nice location to make all of the wiring connections. All you will need to do is run the # 10-2-1 like you mentioned from the brake output post on the junction box to one wire...

  • White LED Light Recommendation to fit a 3 inch by 2 inch Area
    The best recommendation I could make since we don't have a 3x2 LED light in white would be the part # UCL50CB. This is a 2 inch diameter round white LED that would supply a very bright white illumination. For a pigtail harness to install this light you would want the part # A46PB.

  • Flush Mount, Submersible LED Back Up Light Recommendation for a Trailer
    The brightest LED light, flush mount, submersible, that can be used as a back up light, is going to be the round light # BUL23C24B. But this is a 24 volt light and it has 27 diodes. For a 12 volt back up light that is flush mount and submersible would be # BUL10CB or # BUL11CB. For the BUL10CB that you have referenced, you will also need grommet # a70gb, and a wiring harness # A49PB. For the round light # BUL11CB, you would need grommet # A45GB. and harness # A45CB.

  • Reverse Light Wire Color on a 1996 Chevrolet K1500 Pickup to Allow Connection of Back Up Light
    The best way to confirm which wire activates your vehicle reverse lights is to remove one taillight assembly and visually identify which lead goes to the reverse light bulb. To remove the taillight, open the tailgate and locate and remove the two taillight retaining screws. This will allow you to pull out the taillight assembly for access to the wiring. Then, for safety sake, it will be useful to have a helper turn the ignition to the on position without starting the vehicle. Then place...

    Led light # BUL72CB is not certified as use as a backup light. For an LED light that is designed for use as a backup use # BUL10CB. You will also need grommet # a70gb and wiring pigtail # A49PB. For wire you can use # 16-3B-1 sold in 1 foot increments. You will need to wire in the power wire to the reverse light circuit on the 7-Way. For the lights to work you have to have a functioning reverse light circuit on the vehicle side 7-Way.

  • Do Trailer Reverse Lights Require Two or Three Wires to be Powered
    Reverse lights like the part # STL211RCB only need power and ground to function. You would not need three wires ran to the light assembly. Power would need to come from the reverse light circuit of the tow vehicle but you can ground the lights to the trailer frame or using wire to run back to ground of the trailer wiring. The version of the light I would recommend instead though is the part # BUL10CB since this is just a reverse light. For pigtail harnesses you'd want either the # A45CB...

You will also need a wiring harness, # A49PB, to connect to the light. While the light is submersible, the wiring connections will need some attention to keep out water.
