Optronics STL12 Series Fleet Count 6 Inch Oval Sealed LED 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). These lights will extend into the mounting surface and require that a hole be cut into your trailer.

Optronics Fleet LED Trailer Tail Lights w/ Grommets - Stop,Turn,Tail - Submersible - Oval - Qty 2 - TLL12RK

Average Customer Rating:  4.7 out of 5 stars   (190 Customer Reviews)

7-9/16" x 3-5/16" Oval. Waterproof LED trailer tail lights function as stop, turn, and tail signal lights when properly mounted. Durable polycarbonate housing and lens. Reccessed mount with grommet. Accepts included standard 3-prong plugs.


Optronics are the best trailer lights you can buy. Highly recommend.


The Image of these lights are a 10 diode light. They are a 6 diode light and the intensity is hardly visible in the daylight. The lens is "lighter" than the original. These are replacements for a heavy equipment trailer and pose a possible safety and liability issue. Slightly misleading on etrailer's part.

We do have it listed as a six diode light in the description and in the videos for the light.
-- Etrailer Expert Jenny N - 04/06/2022


Shipped quickly. Lights were what I expected and fit perfectly. Easy to install in the standard oval cut out.


Hey not good! The lights are great but the rubber seal is not tight enough. I have lost two lights already backing in the water they pop out of the seal or bounce out going down the road is there a fix because I'm out ro trailer lights? I had to go back to the old ones

Thank you for your review. I am not sure what is up with the grommets unless they were stretched out. We do sell replacements:
-- Etrailer Expert Sierra K - 07/30/2021


Anyone who would like to upgrade their trailer light to LED this is it. Simple to change out fits perfectly. Great product.


These lights were very easy to install. It didn't take me long at all, and the LED lights are so much better. More clear and brighter.


Products were as advertised. I only wish that the lighting products were packaged better instead of just loose in the box with a tire and wheel. The product were apparently undamaged (though I have not installed it yet) but I feel that there could have been broken components with this shipping method.


very easy web site to navigate with fast delivery time. nice job e trailer!


Fit perfectly and was easy to install..


I don't think. I'm not on the payroll. LOL The product is quality. Are bright and easy to see. I replace older LED lights . Kimberly was helpful in making sure I got the lights quickly as reasonable.


Very bright and work great! Excellent upgrade for a 2009 CargoMate Blazer 6 x 12.


Had exactly what we needed and sent out order right away! Good customer service!


These LED lights get the job done. They're easy to install, and after a few years of wear and tear out on the road, inexpensive enough to replace. They're bright and let everyone behind you know that you're braking and turning. Can see from long distance away.


Hi guys,
I'm usually the one answering
These guys are great! My client emailed the link & told me to order these for our horse trailers.
They've held up, to the point, we're not even close to needing to replace them.
We haul quite a bit. These lights have been tried & true, day & night.
When you're hauling a lot of livestock, you want people that have no clue what that entails, to see your lights well before they get near your livestock ; these lights do the job perfect!
We've outfitted 3 separate trailers with this company. We restored wires, lights, & pretty much everything along those lines ;from a 2 horse, to a large stock, & a gooseneck. All the parts come quickly, are all there, & work & fit great. What more can you ask for?!


Price was right and fast shipping. Can't ask for more than that


etrailer makes it easy to find hard to find items, their follow up communications and prices are great.


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


Easy to install and they work as advertised for a great price


Arrived quick. Nothing fancy. Installed easily. Still working great 1 year later.


Lights working fine on my Ranger bass boat trailer.


Perfect replacement taillights. They shine very bright and give my 2004 trailer a refreshed look


Perfect fit, easy install and bright enough to be seen easily.


Lights fit my trailer perfectly.
to install.

  • Do the Tail Lights in Trailer Light Kit # TLL12RK have Reflective Lenses
    Yes, the trailer tail lights in kit # TLL12RK do have reflectors in the lenses. I have included a link to a video review of this light kit for you to view.

  • Hole Size Needed to Install LED Trailer Tail Lights w/ Grommet # TLL12RK
    The hole needed to install the part # TLL12RK will be 6-3/4 inches long by 2-1/2 inches wide.

  • Will Optronics Tail Lights fit 6 x 14 Enclosed Trailer?
    In order to determine if the LED Trailer Tail Lights # TLL12RK fit your 2004 United trailer, you will need to take some measurements of your current lights. If they are 7-9/16" long x 2-3/4" tall x 3/4" deep, then the # TLL12RK would be a direct replacement.

  • Will Optronics Fleet LED Trailer Tail Lights Fit 7" Long x 2-1/2" Tall Cutout
    The Optronics Fleet LED Trailer Tail Lights # TLL12RK themselves actually measure 6-1/2" long and 2-5/16" tall. The rubber grommets are what makes the overall dimensions 7-9/16" long x 3-5/16" tall and since those are the outside dimensions and they are rubber you will have no problems with fit.

  • Replacement for J-67 Oval Trailer Taillights
    For an exact replacement you'd want the part # TLL12RK as I looked up the J-67 and that's exactly what these are. Trailer lights are often made by several companies to the same dimensions etc and this is an example of that.

  • Plate Thickness Compatibility with Recessed Trailer Light Grommet
    The Optronics Fleet LED Trailer Tail Lights w/ Grommets # TLL12RK has grommets that are 1-1/8 inches deep. The plate dimension if you want to use the integrated lip on the grommet is 3/16 inch and if not is up to 1/2 inch. I went out to our warehouse to measure this for you.

  • Are All Optronics Lights Covered by Warranty?
    All Optronics LED lights, such as Tail Lights # TLL12RK are covered by a lifetime warranty. The warranty states that that they will replace the lamp if even a single diode fails. I have added a link to our selection of Optronics LED lights for you to check out as well.

  • Troubleshooting Trailer Turn/Stop Circuit that Doesn't Work
    Most likely the trailer taillight you are referring to has a weak ground. The brighter illumination of the turn/stop circuit of a light draws more than the running light. So if there's a weak ground it will show up with that circuit. Try improving how the taillight grounds to the trailer. You can even run the ground wire up to the main ground harness and you should see it start to work again. I also attached a help article on trailer lighting for you to check out as well.

  • Hole Size Dimension for Optronics LED Tail Light with Grommet
    The light dimensions of the Optronics LED # TLL12RK are 7-9/16" long x 2-3/4" tall x 3/4" deep and the hole size needed is 6.75" by 2.5 inches. I confirmed this with my contact at the manufacturer and I've attached a template they sent to assist.

    We can help with the taillights. I looked up your 2000 Featherlite horse trailer and it uses 6 inch oval trailer taillights like the LED Optronics kit part # TLL12RK which comes with a light for both sides. We do not have window hardware or doors though.

  • How to Determine Correct Replacement Tail Lights
    Thanks for that information, and though I was unable to find any reference to a M1235X tail light we assuredly have an option that will work for you. In order to determine this, however, you will simply need to measure your current tail lights and find the one that most closely matches your measurement, and also know if your lights are surface mounted or recessed mounted. For example, the Optronics Fleet LED Trailer Tail Lights # TLL12RK have a light face which is 6-1/2" long x 2-5/16"...

  • How to Determine Correct Replacement Tail Light Lens for Trailer
    While I can help you determine exactly how to figure out what replacement lens you need, trailer manufacturers don't manufacture a list of replacement parts for models of trailers, and SAE actually stands for "Society of Engineers" and isn't a part number for the light, it just means it has passed certain standards. Having said all that, in order to determine the correct replacement lens, a part number (which may be on the light itself) is needed, or you may be able measure to determine...

  • Locating Replacement Brake Lights for 2008 Tracker Tahoe Boat Trailer
    Trailer manufacturers don't typically keep a good record of the smaller parts they install at the factory like the tail light assemblies. Because of this, your best option is trying to locate a model number somewhere on the assembly itself or simply choosing a replacement with matching dimensions. Looking at pictures of your 2008 Tracker Tahoe Boat Trailer, it appears to be equipped with oval tail lights similar to the Optronics LED Trailer Tail Lights # TLL12RK. These lights measure...

  • Replacement LED Trailer Lights for Truck Lite Model 60 Taillights

  • Correct Trailer Tail Light for 6-7/8" Long Oval Cutout
    It seems like you have the standard 6-1/2" long oval trailer tail lights based on the photo and dimensions provided. Therefore I'd recommend upgrading to the Optronics Fleet LED Trailer Tail Lights part # TLL12RK since this would give you a matching set and they are also LEDs so they will be be brighter and last longer than incandescent.

  • Replacement Taillights for Little Guy 4-Wide Tear Trailer
    The numbers you found have to do with the testing that is done for the lights but from what I could find it looks like your Little Guy 4-Wide tear trailer uses oval taillights so something like the 6-1/2" x 2-5/16" Optronics Fleet LED Trailer Tail Lights w/ Grommets # TLL12RK might work for your application, according to what I was seeing. If your taillights have a different design just let me know and I can see if we have a replacement for you.

  • Can I Reuse my Old Grommet with the Optronics Fleet LED Trailer Tail Lights
    The Optronics Fleet LED Trailer Tail Lights part # TLL12RK comes with the grommets you need to install the lights. If you have existing grommets and the old lights are the same size and shape as the new ones then you can reuse these. That said, I don't really recommend this as the grommets are made of rubber and this degrades over time with UV exposure which can lead to a loose fit and possibly the light falling out. It's best to install new grommets when you install new lights.

  • Will the Optronics Fleet LED Trailer Tail Lights Fit 6-1/2 inch x 2-5/8 Inch Cutout?
    You won't have any issues. The Optronics Fleet LED Trailer Tail Lights w/ Grommets item # TLL12RK has the exact dimensions you will need. The rubber grommet should have no problem fitting inside your cut out. I have linked a diagram below.

  • LED Tail Light Replacements for Jayco Eagle Pop-Up Camper
    We do carry a large selection of LED tail lights and we will undoubtedly have ones that will work for your 2000 Jayco Eagle M-12 UDK pop-up camper, though we do not have a parts list available for specific trailers. The best way for you to find new LED lights would be to measure your current lights and find a close match. For example, tail lights # TLL12RK are 7-9/16" long x 2-3/4" tall x 3/4" deep and recess mounted, while # TLL9RK are 5-1/16" long x 4-9/16" tall x 2-5/8" deep and surface...

    I don't have any available database that would allow me to find what taillights your boat trailer was originally equipped with. Unfortunately, trailer manufacturers don't make that information easy to obtain or disseminate like automotive manufacturers do. However from what I saw online, it looks like your trailer uses standard grommet mounted 6-1/2 x 2 taillights like part # TLL12RK. Quick disconnect pigtails are also included. The lamps will fit in a standard 6-3/4 by 2-1/2 inch rough...

    It is very likely that we have correct LED replacement lights to fit your trailer but I could not confirm your part numbers on the Ranger website or by a web search.

  • Replacement Tail Lights for Trailer
    SAE is just a term for Society of Automotive Engineers and is not indicative of the light you have on your landscape trailer. It is possible the bulb is not designed to be removed, and as such you'd need to just replace the whole light. You can do so fairly cost-effectively, and I strongly recommend going to LED lights such as the Optronics Fleet LED Trailer Tail Lights # TLL12RK or GloLight LED Trailer Tail Light - Stop, Tail, Turn - Submersible - 32 Diodes - Round - Red Lens # STL190RB...
