Optronics STL63 Series Thinline Trailer Tail Light Diagram

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.

Surface-Mount Light

Surface-mount lights install flat against the surface of the trailer, so a hole does not need to be cut into the trailer for the light. This type of light is installed using a flange or bracket that has mounting holes. And mounting hardware is used to secure the light to the trailer.

Video Transcript for Optronics Trailer Lights - Tail Lights - STL63RB Review

Today we're going to be taking a look at part number STL63RV. This is the Optronics Thinline LED trailer light. This is going to serve three functions. It's going to provide your stop light, your taillight and your turn signal light. It's going to feature a sonically sealed waterproof housing and lens unit so it is submersible. The Thinline series is going to have a really nice low profile design so that the light can fit into tight spaces.

It is an LED unit. LEDs are going to make great replacements for incandescent lights. They're going to last longer, burn brighter and they're much more efficient. You don't ever have to worry about replacing the bulbs or the brittle filaments. Optronics is going to cover the LEDs with a lifetime warranty. The lens is going to be made from a polycarbonate material, very strong and very durable.

It's going to have the nice red lens. Here on the back side we're going to have the three-wire pigtail. Your white wire's for ground, black wire's for power, red wire's for stop and turn signal. You're also going to get the black foam gasket. This is going to match the footprint here on the back of the light.

It's got the cutout for the wires and that's going to be installed during the installation in between the light and the mounting surface. You're going to have your mount holes one on each side of the light. Those are going to be separated on center by 14-1/8 of an inch. Your mounting hardware is not included. This light is Department of Transportation compliant. We'll take a look at the overall dimensions starting with the overall length.

That's going to give us a measurement of 15 inches. Measuring this direction at the widest point, that's going to be 1-1/2 inches and then the depth or the thickness, that's going to give us a measurement of about 5/8 of an inch. This light contains nine diodes, power draws at 12.8 volts. For the stop and turn lights we're looking at .350 amps and for the taillights we're looking at .022 amps. We're going to go ahead and hook it up to our external power source. That way you can see what it looks like with power running to it. Again, the white wire's going to be our ground connection, red wire's going to be for the stop and turn and black wire's going to be for our power or for the taillight. You can see here it sends out a nice consistent signal. The multi-diode design is really going to optimize our light output. We'll go ahead and apply our brakes. You can see how that illuminates for a stronger signal output. It's also going to function like that when we apply our turn signals. That's going to do it for our review of part number STL63RB. This is the Optronics Thinline LED trailer light. .

I finally found the exact replacement light for my RV. Thank you e-trailer!


The taillight bars arrived on time and are exactly as represented. I have installed one and it works properly so far. The second one is an extra in case of a future failure while traveling.


Perfect fit for my 2016 Cedar Creek


Product was an identical replacement for my existing light strip on my RV.


I purchased the Thinline LED Trailer Tail Light, and BoatBuckle G2 Tie down Straps, love both products and I am very satisfied with them. Great pricing and great products! Thank you!!


Great lights! Super bright and easy to wire up. I housed mine in a protective wood frame and covered them with wire mesh so they would not get damaged backing up into underbrush. Would definitely buy again!


I have a 2015 Cedar Creek 5th Wheel and 3 of the diodes in the tail light burnt out. I was told by my Father In Law to look on your web site as he has used your company in the past. I was amazed at the number of products that you carried. I was able to find the exact tail light for my rig and ordered it. We ordered the tail light on Friday November 8th and it was delivered to my mail box in Texas on Wednesday November 13th. Outstanding service. Thank you very much.


Perfect match replacement for my Cedar Creek Fifth wheel tail lamp. Delivery very quick.


Perfect fit thanks to your illustration. It even lights up!


Fast service and item was perfect replacement for bad tail light.


All items ordered were in the box to do the needed repairs -
I can't wait to get started - Parts look good - Thanks

The lights look to be made very well and sell at a good price. The best thing about them is the people that sell them! I will buy from them again. Bob

  • Ground Connection for Optronics Thinline LED Lamp # STL63RB
    The lamp is grounded through a dedicated ground wire. The lamp has three wires exiting the rear, a white wire for ground (which is hard to see against the white background), a red wire for the brake lamp/turn signal and a black wire for the running lamp signal. If you click the provided link, you can see a product description video for the Optronics Thinline LED # STL63RB lamp.

  • Can 3-Wire ThinLine LED Trailer Tail Light Replace 2-Wire Light
    You can absolutely replace your 2-wire light with the 3-wire ThinLine LED Trailer Tail Light # STL63RB. The white wire on the ThinLine is for ground, the black wire is for power and the red wire is the stop and turn signals. So all you need to do is splice the wires coming off the light to the appropriate circuits/wires on your trailer, which you can do with the Butt Connectors # 05731-5. I have added a link to a video review for you to check out as well of the ThinLine LED Trailer Tail...

  • Brake Lights, Clearance Lights, and Fender Lights for Enclosed Trailer
    We can get you the right lights for your trailer, but just keep in mind that we don't have a way of knowing the exact replacement lights on any trailer, so if you want to utilize the same mounting holes, for example, you will need to measure the center-to-center mounting dimensions, or you can simply make new mounting holes if you like. From what I can see of photos I looked up of your trailer, they all seem to be surface-mounted lights, so here is a list of what you can use. - GloLight...
