Optronics Trailer Lights - STL14RB

Highlights

  • One Light, 6 Functions: Works as stop, tail, turn, side marker, and both side and rear reflectors.
  • Reliable In Any Weather: Sealed, waterproof construction keeps circuits safe when submerged.
  • Fewer Replacements Needed: 12 LEDs last 50 times longer and draw less power than bulbs.
  • Simple 3-Wire Hookup: Standard pigtail makes hardwiring easy on most trailer setups.
  • Low-Profile Fit: 8" x 2-7/8" surface-mount design installs flush and out of the way.
  • Road Legal: DOT-compliant red lens meets safety lighting requirements.

Features to know about

Reliable Lighting in Wet Conditions: Fully Sealed and Submersible Design

Moisture is no match for this LED Combination Trailer Tail Light. Its sealed, waterproof construction keeps the circuit board and 12 diodes protected, making it submersible and ideal for trailers that see water. Whether backing into a ramp or driving through heavy rain, you can count on consistent, reliable light output without worrying about corrosion or shorting out inside the housing.

All-in-One Functionality for Better Visibility: Six Integrated Lighting Features

This 8" x 2-7/8" rectangular light covers six essential functions in one unit—stop, tail, turn, side marker, side reflex reflector, and rear reflex reflector. That means fewer separate lights to mount while getting full rear and side visibility. It’s DOT compliant too, so you know it meets the safety standards needed for trailer lighting.

Brighter Output with Less Power Draw: Efficient 12-LED System

The 12 built-in LEDs deliver strong illumination that stands out both day and night while drawing minimal power—just 0.252 amps for stop/turn and 0.135 amps for tail functions at 12.8 volts. LEDs last up to 50 times longer than incandescent bulbs and don’t rely on fragile filaments, so there’s no worrying about burnt-out bulbs or dimming over time.

Simple Surface Mount Setup: Durable, Easy-to-Wire Construction

Installing this light is straightforward with its surface-mount design and included hardware. The 3-wire pigtail makes connecting to your trailer wiring simple: one line each for stop/turn, tail/running, and ground. The durable plastic housing with a red acrylic lens stands up to use on the road while maintaining a clean, low-profile look at just 2-13/16" deep.

Tail light was delivered, opened the box and had it installed within 10 minutes. Exactly what I wanted and works perfectly. I order from etrailer whenever I need parts for any of my 4 boat trailers and have never been let down.

by:

Fit just like the one I damaged backing up at the boat ramp. Hope this one doesn't meet the same fate. The work well though. Nice side markers. Very bright. I used the stainless mounting hardware from the old light.



by:

Looks awesome and gets installed on Tue sday



by:

Best trailer lights I've ever owned! 12 months of in and out of lakes 10or 12 times a month. There's no moisture in my lights and,I don't have to unplug them before unloading. Great product u won't b disappointed.



by:

The tail lights for the boat trailer look great and work completely fine. The LED technology provides brighter lighting all around - making driving, turning, braking and backing safer in the daytime and at night!



by:

Had to replace some rusted out tail lights for my boat trailer.
Figured I would try the LEDs for a change.
So far so good.

The lights came quickly, installed easily and quickly.
They work well so far. No problems

Time will tell if they hold up.



by:

Perfect. Direct replacement for my trailers OE taillights. Fit and function as they should.
Only wish I could learn to stop backing into stuff.



by:

The first time I received my order I had the right driver side light and wrong passenger light..called them the same evening and over the phone had another light on the way..received new light today and already installed it looks great..thanks to etrailer for great service and fast shipping first time ordering from them and won’t be my last



by:

This light was an excellent replacement for the Wesbar incandescent light my trailer came with. The mounting screws lined up with the old holes and the wires were color coded appropriately. I had to drill new holes for a grounding screw, other than that the installation was quick and easy. The young lady in customer service was pleasant and helpful. My only suggestion, include some butt connectors in the box, that would have made my installation even easier.



by:

Exact replacement. Perfect. And very fast shipping. Thanks!

Still working correctly. I dont submerge it often, but it has withstood the elements and works fine after a fresh water rinse.



by:

Great Service



by:

I haven't hit the water with this light installed on the trailer but all seems well. The only complaints I have is that the stove bolts that attach the light to the trailer were not stainless steel and the plastic backing on the light, where the square are under the stove bolts head sits is weak. If you turn the nut too aggressively you will strip the light easily. Other than that, time will tell.
I have the same make on the opposite side. Its 6 months old and is working great.
LED lights are the only way to go. Don't waste your money on incandescent lights.



by:

Great product! Highly visible especially at night which is great!

Very fast delivery and reasonable price d.

Lights work great with no issues, very well built. We take the boat out weekly 10 months out of the year, so they are very durable.

Vert good product and fast shipping. Installed and worked from the first time and still working, thanks for a great product. No water intrusion and vibration does not effect it.

Lights still working just fine, no problems.



by:

It's been over a year since I installed the lights on my boat trailer. They've been "dipped" in river and salt water several times and are still doing great. The old style incandescent bulb lights, sealed even, would have burned out long ago. Best lights I have ever had on my trailer. Thanks, etrailer



by:

The light has worked perfectly since being installed. Glad I made the change to LED and etrailer was great in getting me the light, quickly! Thank you very much

Still working just fine!

This trailer light is an LED light and should not have any problems with being submerged time and again. It was very easy to install and worked just as it should. I will not have to replace bulbs every season; how nice.

After one year the tail light is working just as it should. Been through many miles and many launches and retrievals. No problems at all.



by:

Ordered these lights to replace the out-dated lights on my boat trailer. etrailer shipped right away. I liked that. Price was good. I liked that. Pretty simply to hook up. Plenty of wire. I liked that. They were an exact fit. I loved that. I doubt these lights help me catch anymore fish, however; the tail end of my trailer is highly visible now.

They are flawless. Everyone should change their outdated lighting to LED.



by:

This light is an exact replacement for the passenger side tail light on a Back Track Aluminum Trailer for an Xpress Boat. Entire replacement took less than an hour. I was surprised that the replacement light did not include mounting bolts and nuts, but old ones were in good shape, easily removed from old light and installed on new light. Overall no problems or issues.

The light works as well as it did when I installed a year ago. No issuesproblems.



by:

I thought I would have trouble replacing this light on a boat specific custom trailer.
This was not the case thanks to etrailer.com!
Thank-you Thank-you Thank-you!!



by:

Thus far a good light, I am using it as a rear foglight on my truck. It's been surviving the Florida rains, time will tell how it holds up to the elements, I'll write a follow up during our foggy season here. It's a bright light, not too large. My use may be unorthodox, but in the couple of weeks since I installed it still tests good.



by:

Good service. Thanks.



by:

Works really well in fresh water use. Ok in salt water but the warranty is excellent.



by:

The product itself is great, easy install and led lights are bright. downside is I had to fish all but one nut from within the back of the light housing. That was frustrating. They should be taped or separate package for hardware.

  • LED Replacement Tail Lights for Westbar #102641
    Are you sure the problem is the bulbs and not a bad ground or wiring? It's pretty rare for taillight bulbs to both quit working at the same time. But before we get into troubleshooting the LED versions of the lights you have are part # STL14RB for the passenger side and part # STL15RB for the driver side.

In order to make the connections you can get the Deka Heat Shrink Butt Connectors part # DW05744-5.
