Features to know about

Reliable Lighting That Does It All: 7-Function LED Tail Light

This low-profile trailer light covers everything you need in one unit—stop, tail, turn, side marker, side reflex reflector, rear clearance, and rear reflex reflector. Measuring 8-5/8" long x 2-7/8" tall x 2-13/16" deep, it mounts securely to the surface using included studs spaced 2" apart. With only one LED diode in the ONE Series design, it puts out a bright, even glow while drawing less power than multi-diode lights—just 0.36 amps for stop/turn and 0.014 amps for tail at 12.8 volts. It’s efficient, dependable, and built for consistent output every time you hit the brakes or signal a turn.

Durability for the Long Haul: Solid Surface-Mount Technology

Roads bounce and trailers vibrate, but this light’s surface-mount technology (SMT) keeps the LED circuit board steady and protected. The SMT design handles shock and vibration better than older setups and also helps with heat distribution so the electronics last longer. With no filaments to snap or bulbs to replace, the LED setup lasts up to 50 times longer than incandescent lights while staying bright through years of use.

No Worries About Water: Fully Sealed and Submersible Construction

If you ever back your trailer into the water, this light is built for it. The entire housing is sealed tight to keep water out of the circuit board and diode. That waterproof build makes it a solid choice for trailers that see wet roads or full submersion. You can trust it to stay lit when lesser lights fog up or fail after a few dips in the water.

Built to Standard: DOT Compliant and Ready to Go

The ONE Series LED tail light meets FMVSS 108 and CMVSS 108 requirements for automotive lighting, so it’s ready for safe use on public roads. It’s designed as the passenger-side (right-hand) light, with a matching driver’s-side version available separately. The molded plastic housing and red acrylic lens give it a clean look that holds up over time while keeping your trailer visible and compliant wherever you travel.

Fits perfect as replacement on boat trailer
by:
As expected! Excellent quality and has been installed
by:
These lights came OEM on my 2020 LoadRite 5 Starr trailer. The passenger side stop/turn went bad after 1 submersion. I replaced it. The drivers side stop/turn went bad after 3 submersions. I replaced it. The replacement passenger side stop/turn went bad after 2 submersions. In total, the trailer has been submerged 6 times and I've been through 4 of these lights including the originals. Stay far away from these lights.

And for those who might think I'm misdiagnosing the issue, the lights were tested by direct connection to a 12 volt power supply after working my way down the whole wiring harness.
by:
Great on time delivery went together without a hitch ( trailer joke) signals work brake lights work. Thank You
John Gregory.
Order #107636038.

Only issue is the running light will not come on good ground good connections with both wires match what was there before. Puzzled.
by:
Trailer light easy to install and works much better than the original incandescent light.

The led trailer light continues to work flawlessly and remains super bright.

by:
These lights are awesome. I bought a set from etrailer several months ago and while mowing I busted one. Just ordered again from etrailer and as always, I am pleased with the ease of ordering and the shipping process although the shipping could stand to be a little cheaper. Overall, I am pleased and will continue to use these lights until they are obsolete.
by:
Great replacement light for when your one idiot friend backs the trailer in wrong and destroys just one of the lights.

Easy to replace and super bright.
by:
The LED tail lights are an exact match, wire color and mounting, to the standard tail lights I am removing. Easy installation. The instructions are not available but they are not needed. I am pleased with this purchase.
by:
Exactly what I needed, working fine, will shop again for needed trailer parts.
by:
Product was shipped and delivered very quick. Arrived sooner then I expected. Packaged very well and arrived in good shape. No cracks in the lenses. Very happy customer.

Great product and timely delivery.

@Christopher Good to hear! Most people have good luck with these, so hopefully they last many years of good use :).

I ordered late Saturday night and you said it'd be here Wednesday. When i got home from work - there it was - as promised!

Good Set of lights, still working.

These guys are always on the ball. I’m a repeat customer and have never been disappointed.

shipped fast and easy to install....much brighter than the old ones..thanks

Light was perfect match. Cracked out after one season of launching boat 10 times in salt water. Real crap to crap out in 1 season as a “sealed” LED unit.

I am very sorry to hear that! The only bright side here is that these LEDs have a lifetime warranty. You shouldnt be having any issues so I have already sent your information to our customer service team and they will contact you about this.

Do you have a question about this Trailer Light?
  • Recommended Incandescent Submersible Boat Trailer Lights
    Hey Don. For submersible incandescent trailer lights, I recommend the Optronics Combination Trailer Tail Light item # ST16RB for the passenger side and item # ST17RB for the driver's side. These are seven function lights that display stop, tail, turn, side marker, side reflector, rear clearance, and rear reflector. They measure 8-1/16" long x 2-7/8" tall x 2-13/16" deep and have mounting studs spaced 2" apart on center. I know you are specifically requested incandescent lights for your...

  • Replacement Tail Lights For A 2021 Diamond City Trailer
    Hey Don, The STL0016RL16B part number they gave you is just both the driver and passenger side lights bundled together. The # STL16RB and # STL0016RB part numbers are just the specific sides sold separately. We use part # TLL160RK for them both together in one kit.

  • Replacement Trailer Taillight Assembly Kit for 2017 Karavan Trailer
    The taillights you have installed on your trailer are not the standard style that we carry so we aren't able to determine if just the bulbs are replaceable. If you remove the lens you should be able to determine this pretty easily. The # TLL16RK that you referenced would give you all new wiring and light assemblies that have LED bulbs which basically won't ever burn out so this would be a great solution either way. Also it will bolt right up to the mounting bracket holes you have currently. I...

We have Replacement Tail Light and Side Marker Lens for Optronics Combination Tail Light - Rectangle - Red # A16RB a full replacement (front and side) and Replacement Side Marker Lens # AL17RB if you just need the side marker one.

  • Recommended Replacement Tail Light for Boat Trailer
    The Optronics ONE Series Marine LED # STL0016RB you asked about is 8 x 2-7/8 by 2-13/16 inches. I've attached a diagram to assist. The closest tail lights to your 3-3/8x5-7/8 measurements on your boat trailer are the STL57RB for the driver's side and STL56RB for the passenger side. These LED submersible lights are 6-1/16 x 3-5/8 so just slightly larger. For incandescent lights, I recommend the Optronics 6-Function Tail Light - Submersible - Passenger Side # ST56RS and driver's side...

  • Are Load Resistors Required When Installing Optronics LED Lights on Trailer
    Most likely you will not need to add any load resistors when installing the Optronics ONE LED Combination Trailer Tail Light # STL0016RB on your trailer. This should be a simple swap to replace your existing incandescent assemblies with this longer-lasting and brighter LED unit. While most trailers can have their lights switched out for LED alternatives without missing a beat, there are cases where load resistors like # DI34ZR are needed but it's not something that can be accurately predicted...

  • Replacement Trailer Taillight for 1993 Dutchman 5th Wheel
    The closest matching trailer taillight we offer to what you mentioned is the part # STL0016RB for the passenger side and part # STL0017RB for the driver side. These are both 8-5/8" x 2-7/8".

  • Recommended Driver's Side Tail Light to Match # STL0016RB
    The Optronics ONE Series Marine LED 7-Function Tail Light - Stud Mount - Waterproof - Passenger Side # STL0016RB is the right side tail light. For the left side (driver's side), you will want the ONE LED Trailer Tail Light - 8 Function - Submersible - Rectangle - Red Lens - Driver Side # STL0017RB. This is the matching set with the 8th function of the driver's side being the license plate light. These two parts will make your pair.

  • Recommendation To Replace ATV Trailer Tail Lights
    Based on the information you sent, it sounds like you have a trailer that you pull with your ATV that needs new lights. I do not have anything that is an exact match to your dimensions. However, I do have some recommendations that might work. I recommend the Optronics One LED Tail Lights, Item # STL0016RB and Item # STL0017RB. These lights are universal mounts that fit studs. Item # STL0016RB is the right side and has multi-functions-stop, turn, rear reflector, rear clearance, side...

  • Replacement Optronics ONE LED Trailer Tail Light Assemblies
    It looks like you have the ONE LED Optronics lights that use part # STL0017RB for the driver's side and part # STL0016RB for the passenger side. These lights look identical and the only difference is that the driver's side has an extra light on the underside of the assembly which lights up your license plate. If you have a different design or would like to look into something else just let me know. Attached is an installation video for you to check out.
