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.

See what our Experts say about this Optronics Trailer Lights

  • Best Replacement for a Wesbar Tail Light 271594
    Hey Rick. Unfortunately that's correct the Wesbar Tail Light 271594 has been discontinued. Our best option for replacing it is the LED Trailer Tail Light item # STL36RB for the passenger side and item # STL37RB for the driver side. The Wesbar light is about 7" long x 3-3/4" tall x 3" deep. These Optronics lights are 7-7/8" long x 3-1/4" tall x 2-7/8" deep, so they are slightly longer than the old lights but they should fit nicely in the same area. These lights have a Sonically sealed,...

  • Submersible Tail Lights and 4-Way Wiring With Full Length Ground Wires For 15' Aluminum Boat Trailer
    You will need the following components as we do not have a kit with a full length ground wire harness. 4-Way Trailer Harness # A25W2GWB Driver Tail Light # STL37RB Passenger Tail Light # STL36RPG License Plate Bracket # LP10SB

  • LED Trailer Taillight Recommendation for a 3110 Feather Lite Car Trailer
    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.

  • 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.

  • Optronics LED Trailer Tail Lights with 3-Prong Plug
    For an LED-version of the Optronics light # ST66RPG you can use their parts # STL37RB and # STL36RB. These do not include the 3-prong plug but we offer these, right-angle part # A47PB and straight plug part # A45PB.

  • Replacement Trailer Lights for Boat Trailer With Optronics ST36/37 Series Lights
    It sounds like you want to use the Miro-Flex LED Combination Trailer Tail Light - 8 Function - Submersible - 18 Diodes - Driver Side # STL27RB and Passenger Side # STL26RB as replacements for your current lights. That is perfectly fine, and the wires should match up. These are, however, a little longer and shorter when compared to your current lights. If you would like a direct replacement that matches the size of your current lights you can use the # ST37RB and # ST36RB. If you're looking...

  • 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.

  • 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...

  • 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.

  • 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 and...

  • Replacement Tail Light Options for 2002 Pro Craft Boat Trailer
    My technical contact at Wesbar informed me that the submersible light that you have was discontinued a while back so replacement lenses are unavailable. Replacing your tail lights is going to be your best option. 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. If you need the left hand light as well, it is # 403026. Another option is the Optronics Aero Pro Submersible...

  • How to Waterproof Trailer Light Connectors on a Nitro 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 butt...

  • 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 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 looking...

  • What 3-Prong Harness is the Rectangular ONE LED Trailer Tail Light Designed to Work With
    I do have an option for you but the ONE LED Trailer Tail Light part # STL0067RPG is designed to work with a factory installed three-prong connector which we don't offer separately. These are installed at the boat trailer factory to make changing out the taillights easy. Therefore, if you don't already have this you'll need to go with a hardwire version instead for which I recommend the LED Tail Light part # STL37RB for driver or part # STL36RB for passenger.

  • Replacement Tail Light for a Optronics ST-37 LH
    The direct replacement for your Optronics ST-37 LH is the Aero Pro Combination Trailer Tail Light Driver's Side item # ST37RB and passenger side item # ST36RB. These do not have a molded triangle shaped plug so yours must have had that adapter added. It would be easy to swap the connector out when you replace your lights. You'll want to use the Deka Heat Shrink Butt Connector item # DW05744-5. If you're interested in upgrading to the LED equivalent then the correct replacements would...

  • Optronics LED Trailer Tail Lights for 1999 Bass Tracker Boat Trailer
    Since you want to use the Aero Pro Submersible LED trailer tail lights on your Bass Tracker trailer you will want to order part # STL36RB for the right-hand or passenger side and part # STL37RB for the left or driver side. The driver side light matches this design but it has additional LEDs for the extra functions it provides, such as license plate illumination.

  • Will You Need to Re-Wire a Boat Trailer In Order to Switch to LED Lights
    No, you should not need to rewire your whole trailer just to switch to LED lights. Unless you get into doing the swap and discover your wiring is damaged, it should be as easy as mounting the new lights and wiring them in. The LED Tail Light # STL37RB (driver side) and LED Tail Light # STL36RB (passenger side) are great choices to replace your Wesbar 105826 lights. These lights are submersible and splice into your wiring in place of your old lights.

  • Right Hand Taillight Recommendation to Match the part # STL37RB
    The Left Hand Optronics Light part # STL37RB is sold individually. For the matching right hand side light you would want the part # STL36RB.

  • 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.

  • Is the LED Trailer Light Kit Offered With Longer Wiring Harness
    The trailer tail light kits like part # TL16RK all come with a standard 25' long harness so if you need a longer one you'll need to piece together your own kit.
