Optronics STL37RB 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.

Prompt delivery and it fit my trailer exactly. Had to use my original mounting bolts because I didn't discover the new ones hidden in the bubble wrap until I was discarding the shipping box. (not a big problem) May I suggest including wire connectors with the light. A trip to the hardware store would be avoided. 915711

Both products greatly increased the brightness of my taillights which is what I wanted. They have worked since then without fail. The postal service originally lost my order and etrailer didn't hesitate to get another one sent out at no charge. Awesome customer service! 736124

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. 655917

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!! 612782

Ask the Experts about this Optronics Trailer Lights

  • Waterproofing Trailer Taillight Assembly Connections on a Boat Trailer
    What you can do is apply something like Liquid Electrical Tape, # SWC50122, which will insulate, seal, and waterproof electrical connections. I would still recommend wrapping any connections with actual electrical tape as well for extra protection. Another option is to use heat shrink tubing which is usually available just about anywhere tools and/or automotive parts are sold. With this you would first place the tubing around one of the wires before making the connection. Then use a...

  • Comparing Optronics Aero Pro and Glolight Trailer Tail Lights
    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. Light # STL37RB has 23 diodes which will be very bright as you can see in the picture submitted by reviewer Becky P. She is using tail lights # STL37RB...

  • Is there an LED Replacement Available for the Low Profile Submersible Boat Trailer Lights
    There is an LED version to replace the whole light on your trailer, you could use the Over 80 inch, Rectangular Submersible LED Trailer Tail Light, # STL36RB and STL37RB. The part you were looking at is not available in an LED version. I have added a link to all of our LED trailer lights. You can use the icons at the top of the page or the filters on the left hand side to search for LED lights that may suit your need.

  • Replacement LED Trailer Tail Lights for a Sunnybrook 5th Wheel Trailer
    We have many, many LED tail lights that you could potentially use on your trailer. I have included a link to the options for you off to the right. A light like # STL90RB for example will mount to the surface of the trailer using the 4 mounting holes located around the perimeter. We also have light # RVSTL60 that mounts in a similar fashion. You would take the lens off to access the mounting holes but it, too, mounts on the surface. There are so many options available that if you are...

  • What Size Heat Shrink Tubing Should be Used with LED Trailer Tail Light STL37RB
    You would need the heat shrink tubing for 18 to 14 gauge wire # DW05452 for trailer tail light # STL37RB. On a boat trailer I would not use crimp style connectors like butt connectors because the chance that a wire could pull out due to broken strands is enough of a deterrent for me personally. I would make the splices needed, then use some liquid electrical tape, # SWC50122, and follow that up with the heat shrink tubing. That would ensure a tight, waterproof connection.

  • Replacement Lens Recommendation for LED Trailer Light STL37RB
    We don't have an exact replacement for the # STL37RB but we do have a replacement lens for the incandescent version of this light. For that you would need the part # A39RB.

  • LED Trailer Tail Lights that Come with a License Plate Bracket and are Submersible
    Optronics trailer tail light # STL37RB does not include a license plate bracket. This is a left hand side light and not all trailers have the license plate on the left side (though it is most common on the left) so the addition of a bracket would not work for all applications so it isn't included. Light kit # TLL16RK might work for you. The license plate bracket is included and the lights are submersible.

  • Do You Have a Replacment Lens for Optronics Light part STL37RB
    I spoke with my contact at Optronics and they do not have a replacement lens for the LED STL37RB or part # STL36RB. They do have them for the incandescent version, part # ST37RB or part # ST36RB. If you have the incandescent lights, the replacement lens is part # A39RB.

  • Wire Colors and Connection for Trailer Lights with White, Yellow and Brown Wires
    Although wire colors in trailers can have some common assigned functions, such as brown wires carrying running/tail light signals and a white wire commonly being ground, there is not an absolute rule that this has to apply for all wired products. In the case of the Optronics LED Tail Light Kit # TLL36RK the driver-side (left) light does indeed have white, yellow and brown wires. Their single left-side light # STL37RB does as well. These lights use the white wire for ground, the yellow...

  • 7-Wire Jacketed Wiring to Re-Wire a Trailer
    Trailer light wiring is typically in the 16 to 18 gauge range. It is not uncommon to see heavier wire for ground and 12 volt power. We do have jacketed 7-Wire available, # DW04914-1. The wires in this jacketed wire are 12 and 10 gauge but they will still work just fine with any trailer lights. This wire is sold in increments of 1 foot. So for two 30 foot strands you would need to enter 60 in the quantity box. Then just cut it in half when you get it. All the wires are different colors. I...

  • License Plate Bracket Recommendation for Use with the # STL37RB
    The light kit that uses the part # STL37RB is part # TLL36RK. This kit comes with the license plate bracket designed for use with the # STL37RB. As of right now this bracket isn't available separately so your best option would be to get the # TLL36RK. Especially if you are looking to replace both of your taillight assemblies anyway. Another solution would be the part # LP10SB as a bracket as it has mounting holes that are 2 inches apart on center like the # STL37RB.

  • Replacement Lens for Optronics ST-36-RH Tail Light
    From what I was able to find out with my research is that the ST-36-RH that you've got is the same light as our Optronics LED Tail Light # STL36RB; the replacement lens for the STL36RB can be found using part # A39RB. 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. They should be fairly similar, but the important dimensions...

  • 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.

    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.

  • What is the Difference Between Over 80 inch and Under 80 inch Trailer Tail Lights
    A trailer that is over 80 inches wide is required by DOT regulations to have rear clearance lights. An over 80 inch taillight kit, like part # TLL16RK, will have the side clearance light built into it. An under 80 inch taillight does not have the clearance light built in and an additional red, rear side marker light would be required if you used an under 80 inch rated light on a trailer that is over 80 inches wide. Using an over 80 inch taillight on a trailer like yours that is under...

The Wesbar Submersible Right Hand Tail Light # 403076 that you referenced is the closest they currently have to the one that you have on your 2002 Pro Craft boat trailer.

  • 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. I recommend the LED Tail Light for Trailers Over 80" Wide - 8 Function - Submersible - 23 Diodes - Driver Side # STL37RB and Passenger # STL36RB.

  • Number of Diodes in Optronics Trailer Taillights STL16RB/STL17RB and STL36RB/STL37RB
    The trailer taillights part # STL16RB and # STL17RB have 18 diodes and the tailligths part numbers # STL36RB and # STL37RB have 17 diodes so they are very similar.

  • Wire Functions of Optronics LED Tail Light STL37RB and STL36RB
    The replacement light I believe you are talking about is the LED Tail Light for Trailers Over 80" Wide - Driver Side # STL37RB. The brown wire for this light is the tail lights, while the yellow wire is for stop and turn lights. It also has a white wire, which is of course for ground. You will need to match those up to the functions of your trailer's red and black wires; the easiest way to do this is plug in the trailer to the vehicle, have someone activate the functions and you can...

  • Replacement Rear Trailer Light Assembly Passenger Side
    The replacement light assembly that you will need is # STL36RB. This assembly is for the rear right side of the trailer. For your information, the other side or left side of the trailer is # STL37RB.

  • If Trailer Light # STL36RB is the Right Hand Light, What is the Compatible Left Hand Trailer Light
    The compatible left side trailer light you are looking for is the Over 80 inch, Aero Pro Submersible LED Trailer Tail and License Light, 2 Wire, 8-Function, 23 Diode, # STL37RB. This is the same light just for the left side. It has the same functions and specs as the right side light that you have referenced with the exception that the left side light has 1 additional function and diodes for the license plate light.

  • License Plate Bracket Needed for Submersible LED Trailer Tail and License Light # STL37RB
    Since the Aero Pro Submersible LED Trailer Tail and License Light, # STL37RB, mounts on 2 inch centers, one option for a license plate bracket would be part # BK31BB. Another option would be the Trailer License Plate Mount Bracket, # LP5SB. Both of the brackets mentioned have mounting holes that measure 2 inches on center so either one would work for you.
