Features to know about

Brighter, Longer-Lasting, and Efficient: LED Tail Light with 17 Diodes

Say goodbye to dim bulbs and constant replacements. This Optronics LED tail light packs 17 diodes that put out a strong, even light while drawing very little power—only 0.181 amps for the stop/turn signal and 0.047 amps for the side marker at 12.8 volts. LEDs last up to 50 times longer than old incandescent bulbs, so you get a cleaner, brighter glow without worrying about burnt-out filaments or constant maintenance. No bulbs to swap—just dependable performance every time you hit the road.

Keeping Water Out: Sealed, Submersible Construction

If your trailer ever sees wet roads or launch ramps, this light is built for it. The entire housing and circuit board are sealed to keep water from sneaking in. It’s fully waterproof and submersible, so you don’t have to worry about corrosion taking out your wiring or LEDs after a dunk. Whether it’s rain or full submersion, this light keeps working like nothing happened.

Full Coverage Visibility: PC-Rated 180-Degree Beam Spread

Visibility from all angles means safety for everyone on the road. This PC-rated light throws light across a full 180-degree pattern—90 degrees to either side of centerline—so it can be seen head-on and from the side. That wide coverage helps mark both the rear and side of your trailer so other drivers notice you sooner in traffic or low-light conditions.

All-in-One Lighting: 7 Functions in One Compact Unit

Instead of juggling multiple lights, this single unit covers it all—stop, tail, turn, side marker, side reflex reflector, rear clearance, and rear reflex reflector functions—all in one rectangular 7-7/8" x 3-1/4" light. It’s designed for trailers over 80" wide and mounts right on the surface using the included hardware. With its red lens over white LEDs and durable plastic housing, it’s ready for hard use and long hauls.

Simple Wiring and Mounting: Quick Surface Install

No special bracket needed here. Just slide the light over two or three bolts extending from your trailer’s surface using the slots on the back to secure it in place. The 3-wire pigtail makes wiring simple—white for ground, brown for tail, green for stop and turn—so installation is quick and frustration-free when upgrading or replacing old lights.

before and after[old and new]...all is good...



by:

Have been using this model tail light along with the companion port trailer side light for some time. This new unit is a replacement for the same model in which a couple of the LEDs conked out. Overall these are great lights--bright all around and, of course sealed. As usual fine, fast service.



by:

Bought a brand new trailer and from the get go some of the regular lights were intermittent. Finally had enough and ordered LED's to replace them all; have not had a single light issue over a year later. All were direct drop in replacements, fit and look great. Thanks etrailer.com!



by:

I recently purchased this item to replace the incandescent version of this light that no longer worked. Installation was quick and easy. The lights are extremely bright and I can easily tell from the driver seat of my truck that they are working. In addition to this light, I also purchased the STL37RB for the driver side so that I'd have LEDs on both sides of my trailer. I recommend making the jump to LED if you need to replace your old lights.



by:

Everything about the transaction went smoothly. Customer service helped a lot. I was trying to match this light with an existing light. Match looks perfect. Have not installed yet. Waiting for a break in the weather. I don't anticipate any issues.

Works fine. Matching other lamp perfectly.



by:

Before purchasing these lights for my boat trailer, I had gone through two sets of lights with incandescent bulbs trying to find lights that wouldn't fill with water and cause damage to the bulbs and sockets. After a year of use, these lights still never leak when the trailer is put in the water. And the brightness of the LEDs is a huge improvement over the incandescents they replaced.



by:

Super product! Easy to install at a fair price. Super brite LEDs can be seen easily during the daytime.



by:

Great replacement light for older Ranger Boat Trailers. Before the round led lights for the fiberglass fenders there was a Wesbar #105826. Can't find them anymore so etrailer recommended these lights as a replacement. They fit in the fender pretty well. I did have to drill new holes for the mounting bolts lower than the original, no biggie. The visibility is vastly superior to the old incandescent bulbs. You'll probably wonder why you hadn't changed them out sooner as I did. Ordered a pair, first shipment had one broken in it, etrailer sent me a new one quickly and emailed a return label. Communication was quick and pleasant. Highly recommend these folks, have dealt with them previously and will again in the future.



by:

Great units, used these to replace older leaking tail lights on my boat trailer. These are sealed, do not leak and are very bright. Highly recommend them.

Had to replace right side. Not leaking, just stopped working for whatever reason. Still happy with them,



by:

Nicole was GREAT...I ordered the wrong part and Nicole expedited the proper part. I got the first order on Tuesday and called Nicole. She found the right part and sent it to me. I got it today (Thursday) and it is now installed and functioning properly. I'm going on a fishing trip on Sunday so Nicole's quick response was a life saver and saved my bacon!!! Great service!!!



by:

Well I was stranded in California on my way to Idaho with two broken lights. Ordered a set of these for delivery. When they arrived they were poorly packaged together, lenses cracked, split and scuffed. They just threw all the lights in a box with paper. I called to complain and they made me pay for expedited shipping of a replacement set. The product is very cheaply made, thin lightweight and nothing like the Wesbar product I was replacing. Needless to say I'm stuck here wasting my vacation waiting for someone who knows how to pack a box. A little disappointed with etrailer and Optronics quality.



by:

These lights are fantastic, they are brighter than the standard boat trailer lights, able see license light reflection in sun light, and finally they have supplied S.S. nuts and bolts. No rust!!

I would have rated these 5 star if the nuts and bolts would have been standard size instead of metric. Just took extra time to find mm socket to fit!!

Still fantastic lights!!

I had a broken tail light on my trailer so I called a few places and was shocked at how much they were asking for ! taillight, a friend of mine who works for a boat company said look go look at etrailer and I bet you save more than half on the light. Yes I saved a bundle and etrailer had my light at my front door in a couple days. I put the light on my trailer with all the bell's and whistles and really surprised that all the parts came with the light and every thing is good again thanks to etrailer. I know they will have my business for now on for any trailer parts. These people are very professional and responsive and you should really give them a try because you will not be disappointed. Professional company's are hard to find so try them. Thank you etrailer for your help. Larry

Perfect fit, matches the driver side. Delivery was on time, instillation was easy. Thank you guys and gals at etrailer! I'm ready to head for the lake again!!

It's exactly what I wanted.

Received the taillights yesterday, removed the broken one, and replaced both, so the actually matched. Using heat-shrink solder splices to connect lights to the existing cable connectors. Very pleased with how they look, they are very bright.



by:

Great people to deal with excellent service & fast delivery. The lights were put on a 2006 Featherlite car trailer direct bolt on & plug in fit perfect. Here's a few pictures of the lights installed



by:

These are great lights, very bright and visible. Had to get this one as a replacement because someone clipped my trailer and broke the lense. The light still worked, just wanted a sealed one and I was painting the trailer so it was a good time.



by:

Very nice lights, Had to modify some for my installation and with no plate holder it took longer, almost one hour each with all I had to move around,I Like the marker on side it gives it a better look and more noticeable at night. Just what I wanted, Now they can see me!

Just like new! Have had no issues at all Thanks!!

I am totally satisfied with the new Optronics LED replacements for my 2001 RangerTrail. The new lights are approximately a couple of weeks old and they are replacing sealed Wesbar lights. The LEDs have been in and out of the water about 7-8 times with no issues. I can tell you the new LED lights are a lot brighter and crisper than the original lights and throw more light down the road when driving at nighttime. Installation was mostly a breeze. The only issue was I had to re-drill one hole on the RH side because the factory holes were off by about 1/4 inch vertically. Drilling a new hole through the fiberglass allowed the new LED fixture to fit nicely into the cutout of the trailer. No issues with the LH side. I definitely plan to purchase more LED lighting in the near future from etrailer.com as I look to replace the other running lights on the trailer. I highly recommend Optronics LED lights for anyone who plans to upgrade their old, bulb-style lighting. The pictures I have attached are with the running lights on. No brake lights depressed.

I did order a STL36RB but what was shipped looks like STL0066RBG Driver side. please give me a call on my cell. THANKS

Have had them on my boat trailer for 7 years no issues until I broke one with my lawnmower . Definitely worth the investment compared to the old capsule lights that I would replace about every fishing season

  • Best Replacement for a Wesbar Tail Light 271594
    Hey Rick. Unfortunately that's correct the Wesbar Tail Light 271594 has been discontinued. Our best option for replacing it is the LED Trailer Tail Light item # STL36RB for the passenger side and item # STL37RB for the driver side. The Wesbar light is about 7" long x 3-3/4" tall x 3" deep. These Optronics lights are 7-7/8" long x 3-1/4" tall x 2-7/8" deep, so they are slightly longer than the old lights but they should fit nicely in the same area. These lights have a Sonically sealed,...

  • Replacement Tail Light for a Optronics ST-37 LH
    The direct replacement for your Optronics ST-37 LH is the Aero Pro Combination Trailer Tail Light Driver's Side item # ST37RB and passenger side item # ST36RB. These do not have a molded triangle shaped plug so yours must have had that adapter added. It would be easy to swap the connector out when you replace your lights. You'll want to use the Deka Heat Shrink Butt Connector item # DW05744-5. If you're interested in upgrading to the LED equivalent then the correct replacements would...

Though we have another option that is extremely similar, the passenger side that matches the Optronics LED Tail Light for Trailers Over 80" Wide - 8 Function - Submersible - 23 Diodes - Driver Side # STL37RPG (part # STL36RPG) was discontinued about a year ago, unfortunately.

  • LED Trailer Taillight Recommendation for a 3110 Feather Lite Car Trailer
    I looked up pictures of the taillights that are on the 3110 Featherlite trailers and for the LED version of them you would want the part # STL36RB and # STL37RB. It looks like the spare tire mounts for your trailer are something you would have to get from Featherlite though as they aren't like anything we carry.

  • LED Replacement Lights for a Boat Trailer with Wesbar 105826 Tail Lights
    For an LED replacement that is nearly identical to the Wesbar 105826 light you can use # STL36RB for the right side and # STL37RB for the left side. There are also versions that have a plug instead of just bare wires. For the right side use # STL36RPG and for the left use # STL37RPG. I have linked a couple of review videos for you as well.

That is perfectly fine, and the wires should match up. These are, however, a little longer and shorter when compared to your current lights. If you would like a direct replacement that matches the size of your current lights you can use the # ST37RB and # ST36RB. If you're looking...

  • Why are Some Lights Listed as Over 80 Inches and Others Under 80 Inches
    The reason there are trailer light kits listed for under 80 inches and over 80 inches is that there are different lighting regulations for vehicles that have widths that are larger than 80 inches in width than ones that are less than 80 inches wide. You will need to check with your local laws and regulations on trailer lighting also. Check out the LED Submersible Right Hand Light # STL8RB and the LED Submersible Left Hand Light # STL9RB.

    No, it is not plug and play Paul but it can be.

  • Replacement Lens or Replacement Tail Lights for 1997 Jayco Eagle 12 UDK
    The correct replacement lens may or may not be available. We don't have any information on the correct lens cover, so I've linked the page to your options. If you take some precise measurements we may have something compatible. Often the lights used get replaced by the manufacturer over a couple of years so you may need to do full replacements.

  • Replacement Lens for Optronics ST-36-RH Tail Light

With that said, Optronics does make changes to their lights from time to time so I've provided a diagram that shows the dimensions of the current STL36RB that you'll want to make sure your current light conforms to.

    There would be a noticeable difference if you had both the Aero Pro light # STL37RB and the Glolight, # STL117RB right next to each other. You would notice that the Glolight seams to actually sort of glow rather than just light up. This is due to the top and bottom bars that light up solid. Both lights are going to be plenty bright.

  • Replacement LED Lights for Optronics Tail Light ST37
    According to my research the ST37 Optronics light can be replaced by the LED Tail Light # STL36RB (Passenger side) and STL37RB (Driver side). To verify this I do recommend measuring your lights to make sure they have the same (or similar) 7-7/8" long x 3-1/4" tall dimensions. These lights do come with mounting hardware to ensure you have a seamless installation when you replace your old lights. I have added a link to a video review of the lights I highly recommend checking out.

  • Optronics LED Trailer Tail Lights for 1999 Bass Tracker Boat Trailer
    Since you want to use the Aero Pro Submersible LED trailer tail lights on your Bass Tracker trailer you will want to order part # STL36RB for the right-hand or passenger side and part # STL37RB for the left or driver side. The driver side light matches this design but it has additional LEDs for the extra functions it provides, such as license plate illumination.

  • What 3-Prong Harness is the Rectangular ONE LED Trailer Tail Light Designed to Work With
    I do have an option for you but the ONE LED Trailer Tail Light part # STL0067RPG is designed to work with a factory installed three-prong connector which we don't offer separately. These are installed at the boat trailer factory to make changing out the taillights easy. Therefore, if you don't already have this you'll need to go with a hardwire version instead for which I recommend the LED Tail Light part # STL37RB for driver or part # STL36RB for passenger.

  • Recommended Replacement Trailer Stop, Turn and Tail Light for an Optronics ST-36
    Although the # STL36RB light you referenced is the same size and shape as the other ST-36 Optronics lights, it is an LED light. The ST-36 by itself would have a standard bulb. If you need a replacement light with the standard bulb, you would use # ST36RB. To install either version of the light, you will need to cut off the plug and connect the wires from the light directly to the trailer wiring. You can view a standard trailer wiring diagram at the included link if you need it for reference.
