Optronics STL36RB LED Combination Tail Light Dimensions

Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The circuit board is sealed, which means that water will not damage the diodes or circuit board.

PC-Rated Lights

Diagram of light spread for PC rated light

A PC-rated light produces a 90-degree angle of light to either side of its centerline for a total of 180 degrees of coverage. This beam pattern can be clearly seen when you are standing directly in front of the light, as well as when you are standing on either side of the light. When properly installed, this type of light can function as both a front clearance light and a side marker light or as a rear clearance light and side marker light.

Great service! If you have a boat trailer light issue I highly recommend giving these guys a call. I was very satisfied!


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 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.


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.


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


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!!

Perfect replacement.


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.


3rd one I broke


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

The lights are still going strong and you cannot complain about that. Money well spent and thanks etrailer for your help.

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!!

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.


Delivered timely as expected, perfect fit and exact replacement for my Nitro Z8 boat trailer. Wires are exact same color match, all you have to do is remove the broken tail light assembly by removing 2 bolts. Cut to length, strip and attach to existing colored wires, Works perfectly. I recommend using Marine grade heat shrink too. If I break another one I will definitely purchase replacement here. Thanks again.


Exact trailer light I needed. Excellent description of item that is for sale. Good price and shipped quickly. My kids have had the same great experience with etrailer. Will buy again.


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.


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.


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.


Best thing I did with my utility trailer was replacing all the lights with LEDs from 3 or 4 years ago. They are bright, dependable, and last a long long as you don't run them into the side of your shed! Just ordered one of the tail lights again! Same great light, perfect match to the ones bought originally. Same great service from the folks at Ordered Sunday night, shipped the same night and received a couple of days later. Happy with the product, the service, and doing business with etrailer, just not happy with the shed for jumping out in front of me like it did!!!


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,

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!


The Over 80" Areo Pro Trailer light I received a year ago has worked excellent. I have had no issues with this product. Much better light than original equipment. If you are looking to buy new lights I suggest you look at this light very strongly.


Optronics LED trailer lights are really very good. They work well, are very bright, and hold up well, except when you back your trailer into a tree.


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


I ordered a taillight from a big box house and received the wrong unit. The mounting slots on the under 80" and over 80" (width) trailers are different! E-trailer knew EXACTLY what I was talking about and I received the correct light in a few days. They know their business and, just as importantly, they understand the meaning of customer service, which is a lost art these days!


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.

Perfect fit on a Bass Tracker Z9 Nitro trailer. Spliced the new wires into the old coupler and I was done. 30 minutes max. Not the best price I could find until I factored in S&H. Then it was the best of the bunch by far. Excellent product listings and very rapid, fairly priced S&H. I could not ask for more.
