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.

After being told that I'd have to "settle" for a round light fixture for my boat trailer, I went online to try to find something that would better match the original equipment.

Luckily for me, I found the etrailer website, which had the exact match I wanted, so I ordered it. Then, when it was delivered a few days later, I held it up to the fixture on the other side of the trailer, and saw it was an exact match.

Fifteen minutes later the replacement had been installed, and now I have a trailer that looks as it was meant to look.

Thank you etrailer for being there when I needed you.

Your replacement taillight continues to work as intended. Thats a testament to the quality of the sealing, since during the summer the rear lights on my boat trailer are regularly immersed every time I launch and reload my boat. Keep up the good work!

This was the exact replacement tail-lights that was on my 2016 pontoon boat i was
extremely pleased with the speedy delivery once i made my purchase. i have just completed the installation of both trailer lights and it was not that difficult since it
was a exact replacement. i will definitely be ordering from your company in the future for my replacement boat parts. Also the prices for my purchase's were in line with what i expected.

thanks Joey B.
satisfied customer from Alabama




by:

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.



by:

I received the trailer brake light fast and very secure in the package. I have not had a chance to install it but the manufacturing and product integrity looks excellent. I will be doing business again if I need to.



by:

Great all in one light had to splice wires to existing plug but overall excellent! Was for a 2016 TRACKER Pro Guideâ„¢ V-175 Combo boat trailer.



by:

I was able to get the right light, while other dealers seemed lost..



by:

I needed to replace a taillight on my boat trailer. Easily found an exact replacement at etrailer.com for a very good price. Shipping cost was reasonable.



by:

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.



by:

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.



by:

Perfect replacement. Fast shipping and great service. That's why I always choose etrailer.com!

Every time I have purchased items from etrailer it has come quickly and just what I ordered. Very good service.



by:

Great experience from support to purchase to delivery. Exactly the light I needed for my Tracker Trailstar trailer.



by:

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.



by:

Optronics rear trailer lighter was easy to install, their products are quality parts.



by:

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.

Product came promptly to my address

  • 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.

  • Matching Light Assembly to Go With Part # ST37RB
    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.

  • Will The Trailer Tail Light # ST36RB Fit In Place Of a Tail Light With STIAP2 on Lens?
    As the STIAP2 you have sounds like a code on a lens which is used for DOT purposes certifying a light I can not confirm the exact replacement tail light. The code you listed says they are S(stop lamps), T(tail lamps-rear postion), I(turn signals), A(reflex reflectors), P2(clearance, side marker, and identification lamps). I can say the Tail Lights # ST36RB and # ST37RB do also meet these same certifications as your light. The light is 7-7/8" wide, 3-1/4" tall and 2-7/8" deep. It is designed...

    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.

  • Replacement Lens for 7-3/4 x 3-1/4 Inch Optronics Trailer Tail Light
    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. This is the closest match to the dimensions you provided.

  • How to Select Replacement Tail Light For Older Pop-Up Trailer
    We don't have any way of knowing what replacement lens is needed for any trailer, including a 1985 pop-up, and realistically with a trailer of that age you'll likely have to replace the light altogether. It's pretty simple to do though, as you just need to find one that is approximately the same size. For example, if your lights were about 8" x 3" you could go with the Aero Pro Combination Trailer Tail Light - Driver Side # ST37RB and Passenger Side # ST36RB. I have added a link below...

  • 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, the...
