Optronics ST37RB Waterproof 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.


Combination Lights for Trailers Over 80" Wide

Flatbed trailer over 80" wide with combination tail lights

If a trailer is 80" or wider at its widest point, then it requires rear clearance lights in addition to basic trailer lights. These clearance lights indicate the width of the trailer when it is viewed from the back.


To meet these requirements on a flatbed utility trailer where the bed extends past the wheels, you can install combination trailer lights that include the rear clearance function. For proper mounting, the lights must be installed at the widest points on the rear of the trailer - one on each corner.

Product was an easy replacement. I did have to extend the holes in the trailer to make the bolts in the lights line up. You can use a round file or drill the holes out to a larger size. This may not be required for you trailer.

The tail light was wrapped well in the shipping container. It arrived in great condition. It was exactly as advertised. This was a replacement for a broken light. The light fit perfectly into the space on the trailer of the previous light.

I am very pleased with the product that I have purchased from etrailer !!!, the product was everything I expected great prices craftsmanship The aftermarket product was better than the Original part that came on the trailer, I plan to buy the passenger side in the near future. I can't send any pictures of my project because I'm in the middle of a winter storm .lol but I'll make sure I send pictures when I install them , thank you etrailer A1 with me.

These lights work real good because you can see them from far away. Very bright. They sometimes don't last a year, but I have had a few that do last longer then others. I like these, because other drivers can see my boat.

Used the light for a year so far and it works good. Perfect match for the other light.

When the light arrived and I opened the box, it looked perfect. I immediately went outside and removed the old light. I installed and spliced in the new light and then tested it. It worked perfectly! I could not be happier! Thanks, etrailer.com.

  • Trailer Light Side Replacement Lens for Tracker Trailer

  • Replacement Tail Lights for Tracker Boat Trailer Model # T13PRO175P
    Although we don't have specifics about the specific trailer you have, we absolutely have submersible trailer light replacement lenses that will work for you. From what I can find about similar Tracker boat trailers you may have lights similar to the # ST37RB (drivers) and # ST36RB (passenger) currently, so you can use the # A39RB (front lens) and # A36RB (side lens) as the replacement. If you can send in a photo of the lights and their measurements we can absolutely confirm these...

  • Replacement Tail Light Assembly for SAE AP2 04
    The SAE number you referenced really isn't a reliable way to determine the correct replacement light. From our experience and research, the replacement light you're looking for is Optronics tail light part # ST37RB for the driver's side and # ST36RB for the passenger side. These lights measure 7-7/8" long x 3-1/4" tall x 2-7/8" thick and have the Stop, Turn, Tail, Rear Clearance, Rear Reflex, Side Marker and Side Reflex functions. The only measurement that looks off is going to be the height,...

  • Replacement Taillight Lenses for 2015 tracker 1860 Boat Trailer
    It looks like both the front and side lens was damaged. The front lens is part # A39RB, and the side lens is part # A37RB. Assuming that the lamp housing itself wasn't damaged as well, both lenses would work great for you. If the housing is damaged as well, you'll want to replace the lamp with # ST37RB.

  • Replacement Passenger Tail Light for Trailstar Trailer
    Based on my research and after looking at your light in the picture I believe the LED Tail Light for Trailers Over 80" Wide - 7 Function - Submersible - 17 Diodes - Passenger # STL36RPG is what you are looking for.However, the lens does appear to be slightly different than the one you have. The S2T216AP2 on your light is not a part number, so finding an exact match is difficult. In order to know if this light will work on your trailer I recommend taking some measurements.

    I may have a solution for you, but there are not going to be vehicle specific plug and play lights for this application. I recommend using something like the Aero Pro Combination Trailer Tail Light # ST37RB (driver's side) and # ST36RB (passenger side), which are a 7-7/8" long x 3-1/4" tall incandescent multi-function light (Stop, Turn, Tail, Rear Clearance, Rear Reflex, Side Marker, Side Reflex).

  • Need Submersible LED Taillight for Tracker Trailstar Trailer Lamp Part Number S2T216AP2
    From what I've found online, the proper replacement for your S2T216AP2 is # STL16RB for the passenger side and # STL17RB for the driver side. The # ST37RB lamp you'd looked at is a little smaller and is an incandescent lamp, not an LED.

    The part # ST37RB that you have is designed to be used on the driver side of a trailer, or left side, of the trailer. If you wanted the matching assembly to go on the other side of the trailer you would want the part # ST36RB as well. Realistically either light could go on either side of the trailer.

    Can you send me a picture of your taillights? We don't have a way to look up what your trailer would have and there's a good chance it was replaced at some point. If they look like the # ST37RB then you'd need the # A39RB.

    The SAE part number is not the part number of the light, it is just a number on the lens that means that lens has passed SAE guidelines. Based on the dimensions you provided, you're most likely looking for replacement lens # A39RB, which fits the Optronics Aero Pro Trailer Tail Light # ST37RB (driver side) or # STL36RB (passenger side), and measure 7-7/8" long x 3-1/4" tall.

  • How to Determine Correct Replacement Trailer Light Lens or Replacement Light
    The "SAE" on a trailer light isn't actually a part number, it stands for Society of Automotive Engineers and just means it has passed certain testing. The only way to determine the correct replacement lens is with the actual part number of the light, though unfortunately those aren't always readily visible. For example, for parts # ST36RB or # ST37RB you would need the Replacement Tail Light Lens for Optronics ST36RB and ST37RB # A39RB. Without knowing the part number of your light,...

They are essentially the same light, but Optronics has been known to make slight changes to their lights from time to time.
