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.

Hi Ashley, Got two lights to put below the tailgate on my PU Truck, there still working very good. I sent you folks a picture. Thank You Wendell 633939

Every thing working fine
Wendell J - 04/22/2020



I have a 2010 international trailer. I was unable to find exact match parts so I went to etrailer to find comparable parts. These 3 way tail lights were 5 inches longer, as posted in the description, than the ones that were on previously. I just drilled a new hole each for the wires and one screw and used one of the previous screw holes. These lights are bright and I was happy with the flush fit on the trailer. 662483


Bought 2, one defective. It turned on but not bright . Contacted Etrailer for replacement. Excellent customer service, they sent replacement within 5 days. Looks nice 5 inch longer than the original 693658


Received just what I ordered and on time. Thank you etrailer.com 901497

I really like this light. I wanted a very very obvious tail light setup on my old trailer. I mounted these about halfway up the door height. Now I have a modern looking tail light setup, that is insanely bright, mounted above traffic, and there's just no way to not see them. Looks very good, and actually has an OEM feel (it does not look cobbled together on my old trailer). Super easy install. Very happy with this product. 894406


Looks good, exactly what I was expecting, can't wait to install them 868404


Awesome 861279


What a great product. Even before I installed it I knew it would be a life changer. The smooth surface and balanced weight was great. The holes for the screws were perfectly round.The color coated wires were of ample length to easily install. The Red led is magnificent. A beautiful shade o f red. I plan on using it for a 3rd brake light . What a wonderful product at a great value. 835809


looks great , works great 828883


Very good prices and quick delivery. I will definitely buy again 801528


Good addition for extra visibility..Easy Install 793984


Great Service! Replaced my bad LED Tail Lights on my box trailer. I decided to order these 20" LED and replaced the old 16" that my trailer came with. Fast shipping and great service! Thank You! 792579


I am thrilled to receive my product. It took me a month to find this one of such dimensions to fit into my custom Cadillac. Opening up the box and having it in my hands I am happy with the quality, color of materials and luminance. Picture of passenger side; additional brake light. Driver side to follow 786448


Great, I think I will enjoy the install, with all that's going on in the World. Thanks for the extremely fast delivery and help with making my selections! I did make one mistake, the Thin LED Light I order; I think I need to order the base bracket as well! 782819


Excellent product bright LEDs very visible. Installed on an enclosed car trailer to enhance the lighting for driving in congested areas. They work great. Thanks 777529


Very bright, easy to install, so far waterproof. I'm happy! 775126


Received and installed. Working great. 745450


Product was as I was hoping for. Fast delivery and product was just as I expected. Install was an easy install and gives the rear of the trailer the added lighting that I wanted for other vehicles to be able to see my intentions when changing lanes and stopping. Am very satisfied with the purchase and if I need more lighting Etrailer is were I will purchase. All the lighting will be changed at some point including LED side lighting. Prices at Etrailer are some of the cheapest that I have found for quality lighting. 727015


Put this on the rear of our Motorhome. easy to install and makes the brake lights more visible. 706321

easy to install on our motorhome and makes the break lights more visable.

Top quality product 705700


Great way to improve your trailer's visibility for vehicles approaching from the rear. The dimensions of these lights make them a great choice for mounting any flat surface. The number of LEDs are perfect for a light this size. The foam backing provides shock dampening which is important on trailers that are always banging around. 678349


D.O.T. approved, fit and finish looks good, easy install. 3 wires for turn, brake and running lights . This is just what I needed to put on the rear of my 40' 5th wheel .I Just didn't feel comfortable with the 2 small L.E.D. tail lights that the camper came with. These worked out really well. 667407


customer service above average, quick to communicate and provide service to any customer's concern 663635


I usually dont do product review but thought I would give a shout out to an outstanding company. George and the team have delivered everytime I've ordered from them. Excellent service. Will continue to order from this great company. 649834


Very Satified. 601915

  • Can Optronics Thinline LED Trailer Tail Light be Used as a 3rd Brake Light
    You definitely can use the Optronics Thinline LED Trailer Tail Light # STL64RB as a 3rd brake light! You'll need to cap off the black wire, ground the white wire, and then install the Pacer Performance 3rd Brake Light Logic Module # PP20-702 in-line with the red wire to isolate the brake signal from the turn signal. Attached is photo of the installation instructions for the module that you can reference. I also recommend using either the Black # A64BB or Chrome # A64CRB mounting bezel...

  • Adding 3rd Brake Light to Rear of 2016 Honda Pilot
    You can use the Thinline LED Trailer Tail Light # STL64RB as a third tail light on your 2016 Honda Pilot, though to do this you will not want to use the converter you mentioned. Instead, you will want to use the much simpler Pacer Performance 3rd Brake Light Logic Module # PP20-702 run in between the 4-way on your Pilot and the Thinline tail light. The Module will run between your Pilot's 4-way and the LED tail light. You will then ground the white wire of the tail light and run the black...

  • How To Wire the Thinline LED Trailer Tail Light STL64RB As a Third Brake Light
    The Thinline LED Trailer Tail Light part # STL64RB is a three function light with those functions being stop, turn, and running. It has a three wire design with the white wire being ground, the black wire for the tail lights, and the red wire for the stop/turn signals. The stop and turn signals are combined on US trailers which this light is designed to be used on which is why the circuits are on the same wire. I know a lot of customers use this light for a third brake light so if that...

  • Parts Needed to Install 3rd Brake Light on Enclosed Trailer
    The Optronics light best suited to your application as a 3rd brake light is their part # STL80RB which is a single-function LED light. The light # STL64RB that you referenced is a multi-function light (Stop/Turn/Tail) which you do not need. It is necessary that this additional light operate only with brake pedal signals and not with turn signals.
