Features to know about

Brighter and More Efficient Lighting: 10 Super LEDs That Outshine Bulbs

Traditional trailer lights can fade or burn out fast, but this 4-5/16" round LED light delivers lasting brightness with ten red super LEDs under a clear Crystal Clear™ lens. It draws just 0.413/0.026 amps at 12.8 volts, so it’s energy-efficient and easy on your wiring system. There are no brittle filaments to break and no bulbs to replace—just steady, vivid stop, turn, and tail illumination that runs cleaner and cooler than old incandescent setups.

Built for Harsh Conditions: Fully Sealed and Waterproof Design

Moisture and corrosion are the main enemies of trailer lights, but this light is ready for them. The housing and lens are sonically sealed into a single waterproof unit that keeps water and dirt from getting inside. Its all-weather molded plastic construction resists corrosion, making it reliable for years of use around wet roads or launch ramps.

Solid Compliance and Versatility: Meets DOT Requirements in Any Position

You don’t have to worry about placement with this light—it meets DOT requirements in any 360-degree position and complies with FMVSS 108 standards. That makes it a dependable choice for staying visible and legal while on the road, whether you’re running it as a stop, turn, or tail light on trailers less than 80" wide.

Simple Retrofit Installation: Standard 3-Prong Plug Connection

Swapping out old lights is straightforward thanks to its standard 3-prong plug connection. It fits the same plug used by many incandescent lights, so you can upgrade to LED without changing your connector type. The light flush mounts using a grommet for a clean look and secure fit—just add the required mounting grommet (A45GB) and plug (sold separately) to complete the setup.

Long-Term Dependability: Lifetime LED Warranty

Every LED inside this light is backed by a lifetime warranty, giving you peace of mind that once it’s installed, it’s built to stay bright for the long haul.

We are looking for a supplier of trailer parts .. they had what we needed.
We build aprox 60 trailers a year. I am going to take a good look to see what else we can get from them.



by:

Identical size, shape & function to the original taillight on a 2-yo Master Tow dolly. Replacement taillight from the mfg didn’t fit the original taillight bezel. This one is an exact fit.



by:

My experience with Etrailer was excellent again as always. Always appreciate the explanation and videos to confirm correct product and installation before purchase. Delivery is always awesome as well.



by:

I have not hooked it up to power, but I'm sure it will work. THe only disappointment I had was the light I removed had a rubber pad to help seal the screw holes and wire entry to the back of my trailer to keep moisture out. This light does not have that and it is not available from your company.



by:

Exact replacements for my old tail lights.Fit perfectly. They also solved the issue. Tho old tail lights were allowing the blinker current to back track through the clearance lights. One of tail lights had water in it and when it flashed the clearance lights flashed too.



by:

While I've not yet installed these they look like good replacements for the OEM lights. They are the correct style, size and the screw hole placement seems to be correct. My only reason for giving them an average rating is that they don't come with any gaskets. The original lights have a gasket between the back of the light and the wall of the camper. While the light unit itself is sealed the wires come through a hole in the camper wall and without a gasket the possibility of leaks is there. I will likely buy some gasket material from an auto parts store and make my own. No, I don't think the camper sealant will work as well as a rubber gasket.

See what our Experts say about this Optronics Trailer Lights

  • Are Load Resistors Required when Adding LED Lights to a Trailer
    You may not even need load resistors to switch to LED lights. The best thing to do is to try the lights without load resistors first. No need to purchase something you may not need until you know need it. Load resistors such as # DI34ZR dissipate heat through the body of the resistor. Wrapping them with insulation would prevent them from dissipating heat properly. You could put them in a battery or junction box though. Load resistors increase the amperage draw on a circuit. If you are...

  • Can Trailer Taillights be Converted to LED without Causing Dash Error Codes
    Hey Volker, so you can add LED taillights to your trailer and not have to worry about any of the issues that vehicles have. Trailer wiring circuits drawing less amperage due to using LED lights does not cause the same issues that vehicles have when this is done.

  • Pulling a Trailer With LED Lights and the Vehicle is Reading Lamps Out
    Though we do recommend having a resistor on each LED light, we do have other options as well. Since you mentioned having a 7 Way connector, you could use a lamp out sensor adapter like the # 20142 if the trailer is wired with a 7 Way plug or a # C35FR if you have a 4 Flat or 5 Flat plug on the trailer. These have all the needed pieces to trick the vehicle's computers into working with LED lights on the trailer. That being said, you could spice resistors into each of the wires attached...

  • Troubleshooting Trailer Brakes on Horse Trailer
    I'm unsure what you mean by a 'manual' brake controller. Could you perhaps mean that your truck has the factory brake controller built into the dash? If that's the case, some factory brake controllers have proven to be problematic. Some have been so problematic that Tekonsha came out with a tech bulletin showing folks how to bypass the OE brake controller and install and aftermarket unit, which I'll link you to. In my experience, some vehicles with the OE brake controllers are just more...

  • Do LED Turn Signals Need Load Resistors When Installed on a Jeep Wrangler
    Yes, you will need a load resistor for each LED bulb you install on a turn signal circuit. I checked your order and it looks like you bought a total of 4 LED lights, because of that I would recommend you get two sets of LED Light Bulb Load-Resistors # DI34ZR. I attached installation instructions and a couple pictures for this product that shows how it installs.

  • Troubleshooting Running Lights on Trailer Not Working After Swapping to LED Lights
    It is not necessary to install load resistors on a trailer that had it's bulb type swapped from incandescent to LED. Most likely you just need to ground the running light circuit or there is a short on it somewhere to cause it to not function properly. First thing you should do at this point is test the 4-way of the wiring harness with a circuit tester part # PTW2993 for voltage on all of the right pins when the taillight signals are being applied. Just like in the video I attached. If...

  • LED Replacement Light Recommendation For Bargman 68 Round 4-1/2 Inch Trailer Lights
    We have four different round LED stop, turn and tail lights that will fit in the 4-1/2 inch diameter holes in your rear bumper. You could use the Optronics light, # STL23RB, # STL43RB, # STL53RCB or # STL23CCRB. These are 4 inch round lights, but they require a rubber grommet, # A45GB, that allows 4 inch round lights to flush mount in a 4-1/2 inch cutout. Lights # STL43RB and # STL53RCB are sealed, submersible lights if you are adding these lights to a boat trailer. All of these lights...

  • Trailer Lamps of Multiple Trailers Flash When 2020 Chevy Silverado is Switched Off
    Are the taillights on your trailer LED's? If so, this could explain the issue you're experiencing. Ford and Chevy developed 'smart' trailer connectors over the last few model years that seem to be anything but smart. LED trailer lights can wreak havoc with these systems because of the very low power draw of LED lamps. If this is the cause of your problem installing load resistors in the turn signal/brake lamp circuits of the trailer will increase the load on the circuit and solve the problem....

  • Troubleshooting LED Utility Lights Working When Ignition Is On But Turning Off After Starting
    It sounds like some sort of ignition issue in the wiring. You will most likely need to have this checked at a service center for them to determine if your ignition switch may need replaced or if there is an issue with the ECU.

  • Does Connector Need to Change When Converting to LED Trailer Light
    Do you mean the main trailer connector? Or what specifically are you asking about? If you have the standard 3 plug that the # STL53RCB uses like part # A47PB you would not need to replace it as this is not an LED specific connector.

  • Troubleshooting LED Trailer Lights Not Functioning Consistantly
    For your light tear trailer the LED lights could be the issue requiring a load resistor to draw more power than the LED for correct function, but we don't have enough information to confirm since at times they work fine, or not at all, while at other times they blink. It sounds more like a short in your wiring or a bad ground connection. Normally if it were just the need for load resistors you would have the blinking but they would always still have power. It really sounds like a bad...

  • GMC Canyon Trailer Connector Not Reading LED Lamp-Equipped Trailer
    It's hard to speculate, not knowing the model year of your Canyon but I'd be willing to take a guess... In the most recent model years, truck manufacturers such as Ford and GM have begun using so called 'smart' trailer connectors that will not 'read' a trailer unless the connector senses a draw above a certain load. Using a couple of incandescent bulbs on your running lamp circuit would certainly add to the load, and has provided a solution to this issue for others. Others have had luck...
