Highlights

  • One Light, 3 Functions: Provides brake, tail, and turn signals for simple, bright visibility.
  • Reliable In Any Weather: Waterproof, submersible design keeps the light working even on boat trailers.
  • Fewer Replacements Needed: LEDs draw just 0.033 amps at 12.8V and last far longer than bulbs.
  • Built-In Reflector: Flange doubles as a reflex reflector for extra visibility without extra parts.
  • Quick Wiring: 3-wire pigtail connects brake/turn, running, and ground for easy hardwiring.
  • Compact Fit: 5-5/8" diameter, 3/4" thick housing mounts flush for a clean, durable setup.

Features to know about

Brighter, More Reliable Lighting: 7-Diode LED Design

Upgrading from old bulbs changes everything. This round 5-5/8" Optronics LED light uses 7 diodes to deliver strong, even output for brake, tail, and turn signals. At just 0.033 amps at 12.8 volts, it’s incredibly efficient while keeping light output bright and consistent. No filaments to burn out and no dim spots—just a clean red glow that lights up when you need it most.

Fighting Off Water and Corrosion: Fully Sealed and Submersible Build

If your trailer sees rain or water, this light is built to handle it. The polycarbonate lens and housing are completely sealed, creating a waterproof construction that’s ideal for wet environments or boat trailers. You don’t have to worry about moisture creeping in or corroding the wiring—the electronics stay protected so the light keeps working trip after trip.

Simple Surface Mounting: Built-In Flange with Reflector

Installing this light doesn’t mean cutting large holes or dealing with special brackets. The surface-mount design uses a built-in flange that doubles as a reflex reflector, adding visibility even when the light’s off. It mounts securely to your trailer’s exterior using standard hardware (not included) and connects through a 3-wire pigtail harness for brake/turn, tail, and ground. The flange gives it a clean finished look while keeping wiring straightforward.

Durable Construction That Lasts: Polycarbonate Housing and Lens

The tough polycarbonate body resists impact and UV damage better than older glass lenses or thinner plastics. It keeps its clarity and shape over time even after long exposure to sunlight or vibration. With LEDs backed by a lifetime warranty, this light is built for years of use without the maintenance or burnout issues of incandescent bulbs.

Fits Tight Spaces While Meeting Standards: Compact and Compliant Design

At only 3/4" thick with a 4" light face, it sits close to the mounting surface for a low-profile look that doesn’t snag on anything. It meets FMVSS requirements for trailers under 80" wide, so you know it delivers the brightness and visibility needed for safe towing—day or night.

They are flat and sealed and bright, also reflective.



by:

The only thing is they weren’t the same style that was originally on the trailer so I bought two to match.



by:

I ordered a set of these as replacements for older lights. Perfect fit! Bright, and work great!



by:

Had to order with overnight shipping. Customer needed it for a camper. They were leaving within a day and needed it ASAP. No camper dealer around could get it within a few weeks. Was glad I could order it for my customer and have it overnight. Very pleased with the service and shipping.



by:

The lights we ordered came in a very short time and we are very pleased with the product. I would highly recommend this company for replacement parts for your trailer.



by:

Excellent product, easy to install and performs as expected. Used as a replacement for 1969 Apache pop-up camper.

Great fit, easy install and a great looking pair of tail lights for my old 65 Terry trailer.
Exactly what I was hoping for.



by:

Everything worked out perfectly! Quality tail light that hasn't had a problem since we installed it.



by:

I ordered on 1/7. Was finally delivered on 1/24. Not acceptable!

That shouldn't have happened, Mike. Let me get this taken care of for you.



by:

They’ve changed the look of the light slightly, but it was a good replacement for my R-pod trailer. I just changed both lights



by:

Safety update for my antique Shasta. Bright and well made' my only problem was my own failure to order the stainless steel rings to really finish off the install and add some more strength to the light structure; don't be cheap order the rings.



by:

Restoring my old '71 Shasta camper I wanted to upgrade the analog taillights with LED's. These lenses worked great and I was able to use the old aluminum back covers. These lenses are close to the old ones in shape and size and will make the camper safer on the highway. Thx



by:

I think the photos and the video accurately depicted the light. I don't plan on submerging my lights (I installed them on a car vice a trailer), but I believe the lights would do fine. they are completely enclosed. Great communication from Carol at etrailer following purchase.i posted a video of the installed lights to YouTube



by:

Ordered two so I assume they placed both in one bag and the bag has no serial number on it for reference in the future. One was loose in the shipping box and could have been easily broken with no buffer added to package. Shotty shipping.

Hello Terry, this is not typically how these are shipped. Just to verify, is each light you received still intact and usable? If not, I would be glad to send out a replacement to you.



by:

Fast delivery!



by:

I am very satisfied with etrailer and the ordering and shipping of the products, I had questions on the description of the round tail lights so I called etrailer and it was cleared up. The lights are perfect for my application. They are mounted on a small camping trailer that is pulled behind a motorcycle and space is limited so these being only 3/4" thick is great and because they are LED it makes it easier on the motorcycle electrical system. The outside diameter is 5 5/8 inch as on the video review along with all the rest of description is correct. A very nice light indeed.



by:

Great , fast service when I needed them



by:

These were really easy to install. I found that I needed more markers on the side of our 5th wheel trailer (44') I actually posted a few videos of people turning into our lane thinking they had passed the trailer. Connected to the rear and front marker lights and I have had no problems since.



by:

Shipping was quick and efficient. the selection gave me the ability to find exactly what I needed.



by:

Great quality parts
Great service and
fast shipment
I have ordered parts before and have always
Been very satisfied
Thank you to the employees also



by:

We are really happy with this product and it fit our trailer perfectly. Plus, they were easy to install. All in all, it was a nice update to our 1960s Apache trailer.



by:

Easy ordering of the correct light for my R Pod and amazingly quick delivery!



by:

Replaced problematic lights on my vintage trailer. Eliminated bulbs and problems associated with them and replaced with LED. Easy install and quality product

  • Can Optronics LED Trailer Light w/ Flange, Reflector Be Used On 1963 Aristocrat Lil Loafer
    Hey Susan, that's a cool little trailer! Yes, the LED Trailer Light w/ Flange, Reflector # STL13RFHXB can be used as a replacement on your 1963 Aristocrat Lil Loafer. The only thing we don't know are the dimensions of your original lights. These are 5-5/8" diameter x 3/4" thick, so you can compare that to what you have now to see if it is a good match. Where are you headed next once you get the lights replaced?

  • Replacement 5th Wheel LED Tail Light for a Round Red Light
    Thank you so much for your photos. We don't have an exact replacement light for you, but we have something very close. It's the Optronics LED Trailer Tail Light, part # STL13RFHXB. This LED light measures 5-5/8" in diameter (almost exactly what your current one measures) and has the three mounting holes. It features the 7 diodes that your current one seems to have and the same three functions. Most importantly, it's round and fully red. This is a flush-mount design, so there is a difference...

  • Availability of LED Replacement for Round Glo-Brite 9541 Light Assembly
    The closest option we have available to your existing round Glo-Brite assemblies (which are no longer made) is the Optronics LED Trailer Tail Light # STL13RFHXB. This assembly has an overall diameter of 5-5/8" and the light face itself measures 4" in diameter. This unit has a standard 3-wire pigtail (not the 3-prong plug) so you would need to hardwire it to your trailer's wiring at the back. The 3 bolt holes are spaced apart by exactly 4-1/4", so you may need to drill some additional...

  • Replacement Trailer Brake Turn Light for 1969 Apache Mesa Trailer
    While I was not able to find anything that cross referenced with the SAE number you mentioned the Optronics light part # STL13RFHXB is very close to what you mentioned in terms of size and function so it would work great. This is a very common style of taillight found on older trailers like what you have as well.

  • Recommended Tail Lights For 4" Round Hole on Stock Trailer
    With having a 4" round hole I recommend using the LED Trailer Tail Light # STL13RFHXB. This light is 5-5/8" round and will mount over the 4" hole you have. It includes wiring for the running lights as well as turn/brake signals. The recessed lights like the GloLight # STL101RKB are designed to fit the more commonly used 4-1/2" hole.

  • Can a 4 Inch Round Trailer Tail Light Be Riveted On
    The LED Trailer Tail Light w/ Reflector part # STL13RFHXB could hold up to a rivet gun or it could not, there are really too many variables to advise on this but if you were to use the Stainless Steel Trim Ring part # A5TRSSB over the mounting flange I believe that would then allow you to use a rivet gun without breaking the plastic. There is also the option of the Peterson Trailer Tail Light w/ Stainless Steel Housing part # 429800 but this has an incandescent bulb, not an LED.

  • Wiring Trailer Taillights, What Wire Connects to What?
    On the LED Trailer Tail Light w/ Reflector # STL13RFHXB the black wire is for the tail/running lights. The red wire is the brake and turn signal lights and the white is the ground. I have attached below a help article that covers the wiring on trailers as well in case you have any other questions beyond that.

  • Troubleshooting Dim Tail Light On Forest River R-Pod Travel Trailer
    It sounds like there may be a problem with the right LED Trailer Tail Light # STL13RFHXB. As you have already verified you have power going to the light you will want to verify the wire isn't damaged behind where you tested going into the light. There are 3 wires with one ground, one for the brake/turn signal and the last wire for the running lights. If the wire is good all the way up to your tail light then the light assembly will need to be replaced. Since you mentioned it being a new...

  • Troubleshooting New Brake Lights That Both Lights Flash On One Side
    It looks like you purchased and installed the LED Trailer Tail Light w/ Reflector - Stop, Tail, Turn - Submersible - 7 Diodes - Round - Red Lens # STL13RFHXB on a trailer. Typically when this happens it indicates a bad ground somewhere on the trailer, so you'll want to check the ground connection on the right side light, as well as any ground wire for the entire trailer. This would be a great starting point for your troubleshooting, but if all of your ground wires are firmly connected...

  • Availability of Round Trailer Taillights
    You could use round trailer taillights like the part # STL13RFHXB to accomplish what you are looking for. These are surface mount and would attach easily to outside of your camper.

  • Is LED Trailer Taillight # STL13RFHXB Sold in Pairs or Individually
    The LED Trailer Tail Light w/ Reflector # STL13RFHXB that you referenced is sold individually. The reason there is a picture that shows two assemblies is because it shows a picture of it lit up and a picture of it not lit up to show difference basically. If you needed two of these you'd need to order a quantity of two.
