Optronics BUL78 Series LED Utility Light Dimensions

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.


Raw Lumens vs. Effective Lumens

Lumens are used to measure the amount of usable light that is put out by a light source. Raw lumens represent the number of lumens that the manufacturer claims the LEDs are capable of producing. It does not include the light's drive method or the amount of light lost from the lens or reflector. Effective lumens take these factors into account and represent the number of lumens that are actually produced by the complete light assembly, not just the amount of light that the diodes are capable of producing. This light has a 700 raw lumen capacity and produces 490 effective lumens.

7-9/16" x 3-5/16" Oval. Waterproof LED utility light provides bright light to illuminate an area. Durable polycarbonate housing and lens. Surface mount with built-in flange - no panel cutout required. 2-Wire design.

by:

Although labeled as a utility light, I mounted it on the rear quarter panel of our cube truck on both left and right sides to illuminate the side or rear tire area that the two back up lights could not reach. The design was exactly what we were looking for as it was a surface mounted light with only a small 1 inch hole that needed to be drilled dead center for wire placement. We used some three-quarter inch by number eight panhead stainless screws and soldered connections with heat shrink tubing to complete the installation. Ordering was easy and shipping was lightning quick. Thank you very much!



by:

I attached two of these clear utility lights to each aft side of my boat trailer. They are wired to the backup lights on the truck. This gives me excellent lighting when backing down my curving driveway. Clear utility lights are much brighter than regular backup lights and allow me to see the driveway even on the darkest nights.

Lights work great! They have made backing up a long dark driveway much easier. Now I have plenty of light on each side of my boat trailer. Slim profile and water proof just right for a boat trailer.



by:

Excellent!

After a long while of
trying to find a comparable replacement on that A site, I found etrailer.com. They had an exact match to the light that was originally on my trailer. The installation was simple and now I have two matching lights again and one neither is flooded with water.

Unfortunately, the new light has leaked and now has water in it. Otherwise it seems to be doing well.



by:

These illuminate adequately for what I purchased them for. Brighter would be better but they help take some of the guesswork out of backing up in the dark. I’d say they light up as well as my truck’s reverse lights. These are mounted on our 20’ boat trailer.

I am still happy with this purchase and would recommend it to future buyers.



by:

was looking for small back up lights- water tight for boat trailer- these should fit the bill. excellent ordering and email status and delivery- I'll be ordering again if I need anything else. thanks



by:

These I think are going to work awesome. Haven't tested it in the water yet, but as far as brightness these will light up the darkest boat ramp. Installed on the back of boat trailer for night time launch/load, and wired into my reverse lights. Highly recommend if your looking for a great backup light.



by:

I mounted the lights on the rear bumper of my travel trailer. I ran the wire into a storage compartment that had 12VDC. I connected to the power and added a rocker switch. The lights are very bright and the price was good. Can't wait to go camping and put these lights to work. I added a voice activated remote control: when backing up, I yell out the window "Hey Honey, go turn on the backup lights". Hasn't worked yet.



by:

This was so easy, and the prices beat all! thank you so much. oh and delivery was next day.

Still working great, This has to be the best place i have found for light replacements. Fast and great pricing.



by:

I just installed them on my Freightliner MDT as backup lights. Installed 4 of these. They work just as they should. The hole pattern was exactly the same as with the old lights.



by:

Product was as expected, no issues so f ar!



by:

These are very good lights. I just mounted a pair of these below my brake/turn lights on my enclosed trailer, and they work very well. Now I'll be able see when parking the trailer at night, and people will actually know I'm trying to back up now.



by:

Easy to mount LED Bight using as backup on horse trailer.



by:

World class lights. Waterproof and bright!! Will buy again for sure. 4 screws and one hole for wires. My application is back up lights for a trailer.



by:

Good unit for the money and purpose served (reverse light on ATV). Lighting was good as well - as bright as I wanted.



by:

Great reverse light.... really bright and easy to mount and wire for the do it yourselfers.



by:

These are great lights. I bought two of them to use as reverse lights on my boat trailer. They light up bright and allow me to see behind the trailer. I liked them so much I bought three more use as a side marker light and two for cabin lights on the boat. Shipping was nice and fast as well. Thanks etrailer.

Adrian,I too just installed a set of these as reverse lights on my 5x8 utility trailer, based on your input. Thanks, they work great.I ordered these with grommets no need with the flange and the brackets to mount them to. I had to do some minor drilling to have the holes mate but that was no problem.I fished my wiring through the manufacturers existing routes and tapped into my reverse lights, attaching them with a Hopkins 4 Flat extension that I cut in half.Im in business!



by:

I'll give it 5 stars if it wasn't for the long time before shipping...very happy with product, installed four in my horse trailer and make a huge difference. Also installed 6-1/2" Oval LED Trailer Utility Light, Flange Mount, 10 Super Diode - Clear - BUL78CB in back of trailer for safe night horse loading/unloading. see before and after pics



by:

Wanted this light as a 12 volt light in our ice fishing shanty. Works very well, gives off a lot of light and because it is LED it uses very little power. Have had it on for 6 hours at a time and it continues to work very well. It does produce a somewhat straight lite beam so I mounted it on the top corner of the wall/ceiling pointing across the shack and it lights the room well, would work well as it was designed for a vehicle. It is our only light in a 8x12 room.



by:

I mounted these on the rear and sides of my 42' 5th wheel so I can see when backing up. These lights are very bright and light up the area behind the camper very well. Great price too!



by:

Good and bright. Makes backing up a trailer at night much easier.

Product is of good quality, and the lights are quite bright. I like that the housing is plastic, we are in the Northeast, and these lights will see a considerable amount of salt. We will see if the wiring holds up to the road salt!

They made it through an Upstate New York winter mounted on the bottom of a fire truck, no problems at all!



by:

I got these for my trailer for when I am backing down the ramp in the dark and for putting the boat away at home where I don’t have any lights in the carport. Man are these bright and do the job. It lights up the area behind me and I never have to worry about hitting anything while backing down or putting the boat to bed. If you’re tired of not having enough light on your boat trailer look no further.

As for usage, I have had these on for a year now without any issues whatsoever. Also, I take the boat out at least twice a week during the winter and several times a week spring through fall so they get lots of use.

Installed on my 2014 Polaris Ranger as Cab and Backup Lights.

They work great as back up lights for My Polaris Crew



by:

Works good, and is decently bright for a back up light. Like the two wire design and flange mounting. Put it on a boat trailer for back up lights. Did add extra sealant around the flange to clear lens, just to help the factory plastic welded connection. Have had no issues so far.



by:

Bright lights. Added these to my Utility trailer to help with backing into my driveway at night, and to have reverse lights on the trailer. Easy to install. Had to change out the 4 pin plug and wiring on the trailer to the 5 pin and 6 wire. The hardest part was pulling the new 6 wire cord through the frame, much thicker than the 4 wire cord. Take your time and it pulls through just fine.

See what our Experts say about this Optronics Work Lights

  • What is the Brightness Output of the Optronics 6-1/2 Inch LED 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. This light has the highest candela output of any of our 6-1/2 inch oval LED lights. The LED 10 diode light, # BUL72CB, has an output of 123 candela and the LED 10 super diode light, # BUL78CB, has an output of 125 candela. Another thing...

  • Porch Light for Use on a Tear Drop Trailer
    Between utility light # BUL78CB and amber light # STL78AB the better option would be the utility light # BUL78CB. It will be brighter and the white light is definitely going to provide better visibility. We do also have lights designed specifically as porch lights such as # RVPL1C. I have included links to video reviews of these lights for you.

  • Is a Rubber Grommet Needed to Install Optronics Oval 10-LED Trailer Utility Light # BUL78CB
    The Optronics Oval 10-LED Trailer Utility Light, part # BUL78CB, is made with a built-in mounting flange for surface-mount installation where there is no cut-out for the fixture. This item includes both ground and positive wire leads that exit from the rear of the housing. This product does not require a rubber mounting grommet as do some similar products from Optronics, although we do offer a snap-on chrome-finish accent ring for it, part # A78CB. For example, their # BUL72CB is a similar...

  • Brightness of the Sealed, 6-1/2" Oval LED Trailer Utility Light # BUL78CB
    The Sealed, 6-1/2" Oval LED Trailer Utility Light # BUL78CB that you referenced is very bright. This light produces 175 candela which should be brighter than DOT back up lights. I attached a review video for more info. There are no DOT standards that dictate that a reverse light has to be at least a certain brightness so it's hard to say for certain if this light would be brighter than any DOT reverse light. But considering how bright this light is I would imagine it is much brighter than...

  • Can Reverse Light on Trailer Also be Powered with Switch In Truck
    You can do this but you'd need to use a diode installed on the circuit so that the switched power won't backfeed onto the vehicle reverse lights. So what you can do is wire both the reverse light circuit and the switched power source to the input side of the # RM-790 and then the output side to the circuit and you'll accomplish what you are looking for.

  • Will the Optronics Snap-on Reflector Ring # A78RXB Fit STL78 and BUL78 Trailer Lights
    I spoke with my contact at Optronics and verified that the Snap-on Reflector Ring, # A78RXB, will fit the BUL78 and STL78 series LED trailer lights. The configurations of the lights are the exact same. The only difference is one is a backup light (BUL78) and one is a stop, turn and tail light (STL78). It is not customary to put a red reflector ring around a clear light, but there is no reason why you could not do that. Keep in mind, the # BUL78CB is a utility light, so it will have a...

  • Recommended Optronics Assembly for Adding Backup Lights to Sprinter

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,...

  • Is Optronics Oval LED Trailer Utility Light BUL78CB Submersible
    You can submerse Optronics trailer light # BUL78CB. The housing and lens unit are sealed. You will also need to make sure the wiring gets sealed up water tight. You can use heat shrink tubing or coat the connections in liquid electrical tape, # SWC50122. I have included a link to a video review for this light for you.

  • How to Wire in the Optronics Sealed LED Utility Light # BUL78CB as Trailer Reverse Lights
    You would not need to install a relay to use the Sealed Optronics Lights # BUL78CB on your trailer. These LED lights draw such a minimal amount of amperage that all you would need to do is tap into the reverse light circuit of your trailer wiring and you would be good to go. I attached an FAQ article on trailer wiring for you to check out also.

  • How Would Reverse Light Install on a Boat Trailer
    You would need to have a reverse light circuit ran to your trailer to power reverse lights. If you have a 5-way flat or 7-way trailer connector currently then that circuit is already present. If you have a 4-way harness then you would need to install the part # 20036 on your tow vehicle to allow you to have that circuit. The # BUL78CB is a white light that would work well for this.

  • Stop, Turn, Running and Reverse Lamp Compatible with Optronics A78RXB Snap-On Reflector Ring
    The # A78RXB snap on reflector ring you mentioned is only compatible with Optronics STL78 series taillights like the # STL78RB , none of which has the provision for a reverse lamp. Your best bet would be to use a # STL78RB stop/turn/taillight and a separate reverse lamp like # BUL78CB which is a surface mount lamp like the # STL78RB.

  • Why is the Optronics LED Clear Oval Trailer Utility Light # BUL72CB Not Certified as a Backup Light
    The Sealed, 6-1/2 inch Oval LED Trailer Utility Light, Flange Mount, 10 Super Diode - Clear, item # BUL78CB, does not meet DOT FMVSS 108 requirements, for backup lights so it cannot be sold as a backup light. That does not mean that the light cannot be used in that situation for applications where a DOT requirement does not need to be met. In short, the Trailer Utility Light, item # BUL78CB, can be used as a backup light, but if your trailer needs to meet DOT requirements you will need...

    Optronics light # BUL78CB is a utility light so it is not DOT approved to be used as anything other than that.

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.

    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 #...
