Optronics Light Dimensions

Sonically 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 housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.

I wish I would have discovered and specifically this light 2 months ago! I am redoing a snowmobile trailer and wanted to update the lights. I have less than 2” to work with. After ordering multiple style of lights I finally discovered thin light gold! This saved my project and works great! Now all I need is snow!

It has been over a year since my purchase from and the lights still work great! I have put these lights to the test and they have held up wonderfully! Couldn’t be more happy! I will definitely be a return customer for future projects!

I replaced all of my exterior travel trailer lights for LEDs, and etrailer was my go-to source. These thinline strip lights were a new addition, because I wanted higher visibility with the tail lights.
The thinline lights were tied in with the existing tail light wiring and work great. What I find most attractive is the clear lens and slim profile, so they are not detracting from the white fiberglass trailer's design.
Also pictured are 4 Tail Lights (STL78RB) with chrome accent rings (A78CB).


Very bright, nice looking lights. Affordable and well made.

I used these for auxiliary towing lights on my 2018 Jeep JKU Wrangler. I have them wired to both a lead going to the front of the Jeep where they can be attached to the motor coach providing independent running-stop-turn lights for the Jeep while in tow as well as to a short trailer connector on the rear. The later allows me to plug them in to my trailer tow connector and they operate in parallel with my OEM lights when the Jeep is not being towed.


Even though it has a clear lens, it is a very bright RED light. I installed it at the center rear of my boat trailer to replace my broken one. I only connected the Tail wiring and not stop/turn as the trailer stop/turn lights are on the corners.. I've only used the trailer twice since the install (submerged backing the boat into the lake) and so far, so good.


When I transport my dirt bike, it obscures the tail lights on my Jeep. So I needed a tail light that I could mount to a motorcycle rack that fits into my hitch receiver. This product was a perfect fit. It’s thin, bright, easy to mount and looks good. etrailer has always made it easy to find, purchase and ship parts for what ever project I’m working on.


3rd time using these lights, great prod uct.


I need to figure out what I'm going to do, but these are garbage. They have already burned out.

Thanks for the review! The good news is that these lights come with a warranty. I have sent your information along to our customer service team.

I've liked them so much I've made them the standard on my trailer builds.

Here is some pics. Go ahead and use if needed


Great lights


was as reported .worked good for pulling machinery that isnt manufactured with lights


I installed two of these, one on each side, on the back of my Gemtop canopy to replace the stupid looking (and broken) tail light that was on the top center just under the lumber rack... (I see the conflict). These things are nice and bright, and the unique light pattern makes my truck easy to track or follow when caravanning.


Great Product. Increases safety.


Works great, just a little brittle. I wanted to use some screws at the end to mount it in addition to the tape, broke with little pressure. My fault as it wasn't designed that way. I would buy again, just use the tape only.

This is a common issue when installing the lights with screws using a drill - you are not alone! When installing these - and other trailer lights - with screws, it is best to hand tighten the screws so you have more control over the pressure.

Great product to replace tail lights on my enclosed trailer. Looks like a good quality build, time will tell on LED life.

*wish etrailer would pickup more size options in clear LED tail-light strips, the ones I replaced where 17”. Did not see any clear ones on the site this size.


I sold the trailer the lights were purchased for before the led light package was installed. The lights met my expectations.


Slim, very bright and excellent way to make your trailer visible


Lights were easy to mount and wire up! very bright.


I plan to use two of them for a custom trailer I am building. They have not been hooked up yet, but they look to be exactly as described. They seem to be great quality lights with excellent waterproofing.


Tested them out on a battery and scared the heck out of myself. Thesent lights are hard and look amazing. Don't look straight at them when testing, they are very bright.


The thinline lites are a great addition to my toy Hauler. this is the 4th set i bought. I have them on all my trailers


lights work very well. installation was easy. the lights are nice and bright and easy for people to see. quite pleased with them.


Product is great quality and shipping was handled quickly!


Product worked great! Sold the trailer a month later.


Got my lights on time, installed them same day and they are great. They are even brighter than the factory installed. Will be buying from this company again.


This is second order. All orders were excellent, on time and quality of product. I will most certainly be using you again in the future
