Optronics ST70RB Oval Sealed Tail Light Diagram

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.


Recessed-Mount Light

Recessed mount light

Recessed-mount trailer lights install underneath a housing or a grommet (A70GB - sold separately). These lights will extend into the mounting surface and require that a hole be cut into your trailer.

Perfect fit for my Eagle boat trailer. FYI, I bot the lights hoping that the replacement would fix several lights out problems that made no sense. I installed the replacement light and everything started working. Great!



by:

Fantastic service! I had a trip to take... leaving today, but discovered a trailer taillight out yesterday! Called several local parts departments and no one had a replacement. Went online just before noon, ordered this replacement light and paid for next day shipping...my taillight arrived just after 10 am today and I was able to leave for my trip on time with a good taillight!!!



by:

I ordered some replacement parts for my utility trailer. My experience could not have been better. First of all, I ordered on the phone, reaching a friendly voice. Quickly the order was processed, which was also followed up with a confirming email about the order. Not long after the order that day, I got a message from another associate who advised the order is shipped and would be arriving in just a few short days. When I got the order, the parts were carefully boxed to prevent damage. The quality of the parts was excellent. I installed the parts, and tested, finding them working as expected. It goes without saying my order experience was friendly, efficient and reliable. I would recommend others consider using this company. I would not hesitate to use them again in the future should I need anything they offer.



by:

Parts were in stock and received them quickly. E trailer is my go to for all my trailer needs.



by:

Hard to find part, in stock! Perfect replacement for old part with fast shipping. Keeping trailer original lighting so as to not have to rebuild electrical system.

@Stephen Thank you for the update Stephen. Glad to know you have not had any issues over the last year.


by:

Great product, decided to stick with incandescent vs. LED due to lower cost and infrequent use of this utility trailer. Great product, along with rubber grommet and replacement wires, this includes dielectric grease already in place. Quick and easy replacement installation. E Trailer is a great source for all my various utility, boat and RV trailers. One stop shopping.



by:

After one year it still Works great and is an operational tail light for our trailer!



by:

I had difficulty initially finding parts I needed for my 32 year old MasterCraft trailer anywhere. But etrailer came through for me. Great service. Fast delivery. And fantastic prices. And, most importantly, they had the parts I actually needed. I'll be using them again and recommending them to others.

Great trailer lights, easy to install, and durable! Perfect fit!! Thank you etrailer!!!

This is a high quality light that was a perfect replacement for my utility trailer. Shipping was fast and the price was very reasonable. Very happy with my purchase. Would highly recommend.

Needed to replace the taillights on my stock trailer. Great dealing with the good folks at etrailer.com. The taillights I got from etrailer were easy to install and are very bright. I will do business with these folks again!!

Great! Good product!

Lost light and rubber grommet on road trip with motorcycle trailer. The replacement light and grommet ordered fit well and works great. Easy ordering and delivery as expected. Video was very helpful. Only issue I see is the rubber grommet is not as snug as original, however fit fine.

I wish I had a picture of the signal
light flashing.

Attached is a picture of my 1958 Alumniacrafet w/Linex inside, Powdercoat outside, and new oak seats.

I was going to take it on the maiden voyage and realized the lights on the trailer had burned out. Luckily etrailer's website was very easy to use and offered a plug and play replacement.

The parts arrived to NW Montana on time. My wife and I were able to see the Arctic Grayling spawning up Rogers Creek from Lake Rogers in NW Montana. Thousands of fish in a four foot wide, ice cold stream, narrowly escaping a sow black bear that was eating only the cheek fat and leaving the rest for the bald eagles.



by:

I bought a trailer a year ago and it had some lights out, i tried going locally for replacements but couldn't find what i needed, tried etrailer online and they had the lights for my particular trailer that were exact replacements, i ended up going with the led option and they are still going strong today! etrailer is now my go to site for anything and everything trailer, Thank You etrailer!



by:

You can always find the products you need for trailers, and the price is fair.



by:

Perfect replacement for my bad one



by:

My order arrived a day early and was the exact replacement I needed. I am very happy with the service I received from trailer.

Quick Shipping...Exactly as described.

Always happy with etrailer

See what our Experts say about this Optronics Trailer Lights

  • Recommended LED Trailer Tail Light Version of the Optronics Oval Stop Turn Tail Light # ST70RB
    You bet there is! The LED trailer tail light you are looking for is the # STL70RB. The only difference will be the depth because the LED light will not need the amount of space that the incandescent one does to accommodate the bulb. They will both use the same plug and grommet thought. I have linked it to this page for your convenience.

  • Recommended Clear/Frosted LED Replacement Backup Light Equivalent to Optronics ST70RB
    For backup lights for your horse trailer I recommend the # BUL12CB Optronics LED Backup Light for Truck or Trailer - Submersible - 6 Diodes - Oval - Clear Lens. This has the same dimensions as the # ST70RB at 6-1/2" long and 2-1/4" tall. The depth is less at 1-3/4" since it is an LED and not incandescent. If you want to replace the grommet when you replace the lights, I recommend the #a70gb PVC Grommet for 6-1/2" Oval Trailer Tail Lights. I have attached a video review for your reference.

  • Availability of Rubber Grommet to Use with Install of Optronics Trailer Taillight # ST70RB
    Hey Bob, yes we do have a rubber grommet that you can use with the Optronics trailer light part # ST70RB with the part # a70gb.

  • Will the ST70RB and the STL72RB Both Fit on the Same Sized Light Housing?
    To answer your question, both of the # ST70RB and the # STL72RB are 6-1/2" long x 2-1/4" wide x 2-3/8" deep lights; the main difference is that one is an LED light while the other is an incandescent. I was able to find some information on your TruckLite 60283 light and the best match to replace that light is the # ST70RB , since your trailer light system is wired for incandescent lights. If you wanted to switch both lights over to LED, you would use # STL72RB but you would likely need...

  • Replacement Lights and Light Kits for Tow Ready Cargo Carrier # 63153 and # 63155
    You are correct. The light kit, # 20174, for Tow Ready Cargo Carriers, like # 63153, are sealed and there are no replacement bulbs. The lights used in the kit are 6-1/2 inch Oval Trailer Stop, Turn and Tail Light, 3-Function, # ST70RB. We also have complete replacement light kits. First is the 20174 kit you have referenced. The other is the LED Light Kit for Draw-Tite, Tow Ready, and Rola Railed Cargo Carriers, # 98174LED. The only difference is that the 98174LED light kit uses LEDs and...

  • How to Determine if Trailer Light ST70RB Will Work as Replacement.
    We would have no way of knowing a specific trailer light on any trailer, including your 1993 Heritage, so the best we can offer is to tell you how to determine you can use the Optronics Trailer Tail Light # ST70RB. Just measure your light, and if you get the same dimensions - 6-1/2" long x 2-1/4" tall x 2-3/8" thick - then you can use this light. It will also require 3-Wire Pigtail # A45PB or # A47PB.

  • Lights that Fit MT-BOX65 Trailer Light Mounting Box
    We had the chance to use the mounting box part # MT-BOX65 to install lights on a trailer (see attached install video) and we used the grommet # a70gb and the lights # ST70RB and we found they fit and worked well.

  • Recommended Backup Light Similar to the Optronics LED Oval Trailer Tail Light
    The Optronics LED Backup Light part # BUL52CB will work great as a backup light and can be used in conjunction with the Optronics LED Trailer Tail Light part # ST70RB. They are both oval in shape and have a high diode count so they will be very bright.

  • Replacement Trailer Taillight Recommendation for Bargman 4006001
    The correct replacement light you need for the Bargman 4006001 that you referenced is the part # ST70RB. The Optronics light, part ST70RB, is a direct replacement for the following lights: Uni Bond # SE2238R Wesbar # 203561 Truck Lite # 60202R Grote # 52182 Peterson # 421R Bargman # 40-06-001

  • Is 6-1/2" Oval Trailer Stop, Turn and Tail Light, 3-Function # ST70RB Sealed
    Yes, since the Sealed, 6-1/2" Oval Trailer Stop, Turn and Tail Light, 3-Function # ST70RB is sealed it does not have a replaceable bulb that you could swap out. The good news is this is a lower cost assembly so a replacement bult would be about the same price as this.

  • Is Optronics Trailer Tail Light # ST70RB the Same As Petersen Trailer Tail Light # M421KR
    Yes. The M421KR is a Petersen part and the Optronics equivalent is the Sealed, 6-1/2 inch Oval Trailer Stop, Turn and Tail Light, 3-Function, # ST70RB, that you have referenced. For a complete set up, you will need Rubber Grommet # A70GB, and Straight 3-Wire Pigtail, # A45PB.

  • Trailer Replacement Light for a Model J-65 Tail Lamp
    I have a couple of options for replacement lights. The larger one is going to be an 1/8 of an inch off of your Model J-65 tail lamp. It is the Optronics Trailer Tail Light item # ST70RB you were looking at. This light is 6-1/2" x 2-1/4" and has a 3 prong plug. I have linked a diagram below that shows the dimensions of this light. We do have a slightly smaller light that is 6-1/2" wide by 2-5/16" tall it is the Miro-Flex LED Trailer Tail Light - Stop, Tail, Turn - Submersible - 12 Diodes...

  • Are the Wesbar 108121 and Optronics # ST70RB Lights Interchangeable with Light Kit # 98174LED
    Wesbar light 108121 is now a discontinued item but the Optronics # ST70RB is a direct replacement for it, and yes, this 6-1/2-inch oval 3-function light will work great as a replacement part for the cargo carrier lighting kit # 20174. For brighter light output and lower power demand you can change over to an LED-type lighting kit such as # 98174LED. LEDs do cost more than standard incandescent lights but they offer higher efficiency, brighter output and require no periodic bulb changes.

  • Bargman 40-06-001 LED Replacement Trailer Tail Lights
    Yes we do! The LED light that is comparable to the Bargman 40-06-001 and the Optronics # ST70RB that you referenced is the part # STL002RB with the staggered 3 pin connection. We also have the kit # TLL12RK which comes with the same size lights, grommets, and pigtails. The only differences are that they have a slightly different lens design and they use 12 diodes as opposed to 1. Installation videos have been linked for you to reference as well.

  • Troubleshooting Left Turn/Brake Circuit on Trailer
    If you have tested the left turn/brake pin on the trailer connector on the vehicle, and found that it works correctly, then the problem is in the left turn/brake lamp circuit on your trailer. Start at the trailer connector itself, checking for excessive corrosion or damage. Clean, repair or replace as necessary. If you have a 4-pole trailer connector, the point where the wire enters the plug itself is a common failure point. Typically, the left turn/brake circuit is a yellow wire. Trace...

  • Replacement for Truck-Lite Trailer Tail Light 60210R
    Yes, the Optronics Trailer Tail Light part # ST70RB will be a direct replacement for your Truck-Lite Trailer Tail Light part 60210R. They both have the same dimensions and the plug is the exact same. If your trailer lights are not working then make sure to check the bulbs, fuses, and wires as well. If you can send me a photo of the marker light you are referring to then I would be happy to let you know how it is removed.

  • Replacement Light for Optronics ST70RBTK Trailer Tail Light with Mounting Bracket
    For a replacement light that is the same size as your ST70RBTK I have two options. One is the Optronics Trailer Tail Light - Stop, Turn, Tail - Submersible - Incandescent - Oval - Red Lens # ST70RB and the other is the Optronics LED Trailer Tail Light - Stop, Tail, Turn - Submersible - 48 Diodes - Oval - Red Lens # STL70RB. The real difference here is sticking with an incandescent light or adding LED lights. Both of these lights have the same measurement of the discontinued ST70RBTK which...

  • Mounting Dimensions of the Optronics 6-1/2 Inch Trailer Light # ST70RB
    I took a few measurements for you that I think will help. I have attached a diagram and made a short video for you showing the dimensions and the light. I believe this light will work with your bumper without having to cut out a hole in the back of the bumper. When the light is mounted in the grommet, portion of the light that extends past the wall of the bumper will only be 1-11/32 inches. You should have no problem installing this in your 2 inch x 4 inch bumper.

The Optronics Miro-Flex Trailer Tail Light # STL22RB is very similar to the # ST70RB, and could be used as a replacement light to change from incandescent to LED.

If you can find that part number on your Bargman light, then we can be sure that this light is the correct replacement. Even if your Bargman light has a different part number, # ST70RB will very likely work. The dimensions of the light are 6-1/2 inches long x 2-1/4 inches wide x 2-3/8 inches deep. If your current trailer light is approximately the same size, this light will work...

    Yes, the Optronics Trailer Light, # STL70RB, will replace the Wesbar 203561 to upgrade to LED lights. You will want to check the factory grommet when you remove the light, if the factory grommet is in good condition you can use it with the LED upgrade. If the factory grommet is worn or shows any signs of damage, now is the time to replace it. You would use the Optronics Rubber Grommet, # A70GB. Same thing on the 3-prong plug connector, check it also to make sure it is in good condition....

  • What is the Difference Between the Peterson 417-49 and the Optronics A45PMB 3-Wire Pigtails?
    Not really. They're just made by different companies. The 3-Wire Pigtail for Optronics Trailer Lights item # A45PMB and the Peterson item # 417-49 are both made out of 20 gauge wire. They each have the female weathertight plug and are 10" long. I would go with the most affordable option.
