When you need one light that does it all, this Optronics Aero Pro tail light steps up. At 7-7/8" long by 3-1/4" tall, it packs eight functions into a single, low-profile housing—stop, turn, tail, rear clearance, rear reflex, side marker, side reflex, and a built-in license plate light. The red rectangular lens gives your trailer a clean, uniform look while meeting DOT requirements. With just two 1157 bulbs drawing 2.3 amps for stop/turn and 0.9 amps for tail at 12.8V, it delivers bright, dependable output without overloading your wiring.
If your trailer sees water, this light is ready for it. The sealed, waterproof housing keeps moisture out so the bulbs and circuit board stay protected even during full submersion. That means less worry about corrosion or shorting when you launch or haul in wet conditions. It’s a solid choice for anyone who needs reliable lighting in harsh or damp environments.
Road vibration and bumps can destroy weak lights fast. This Aero Pro tail light uses shock-proof sockets that cradle the bulbs and protect them from damage caused by impact or movement. The durable plastic housing with a screw-on lens stands up to everyday use while keeping maintenance simple—bulbs are easy to replace when needed.
Getting this light mounted and wired is simple with its stud mount setup and included hardware. The studs are spaced 2" on center for a secure fit on most trailers. Its 3-wire design makes wiring easy—just hardwire it into your existing 12V DC system. Once it’s on, you’ve got a clean-looking light that’s easy to service and built to last.
Beyond performance, the Aero Pro design gives your trailer a more contemporary look without sacrificing function. The built-in reflectors mean no extra parts or stick-on reflectors needed. It’s a neat upgrade that keeps things simple while improving both safety and appearance.

I am very satisfied with the product and the service I received from etrailer. I will certainly recommend etrailer to others. Thank you.
Perfect replacement. Fast shipping and great service. That's why I always choose etrailer.com!
Optronics rear trailer lighter was easy to install, their products are quality parts.
Very helpful
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.
Absolutely wonderful service. Had exactly what I needed for my trailer, ordered it and it was here within a week. Customer service even notified me when it was shipped as well as when it was delivered. Would definitely buy from them again!
Great experience from support to purchase to delivery. Exactly the light I needed for my Tracker Trailstar trailer.
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.
When I needed a replacement you had the right product and it was delivered timely…
Thanks
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 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.
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.
Great all in one light had to splice wires to existing plug but overall excellent! Was for a 2016 TRACKER Pro Guide™ V-175 Combo boat trailer.
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.
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
happy with taillights and delivery
Ordered the ST37RB trailer tail lights to replace tail lights on my boat trailer . I am very pleased with them as they were exactly the same as original lights therefore no need for modifications when mounting. Ordering was easy and arrived on time
I was able to get the right light, while other dealers seemed lost..
Got what I ordered bvery fast
The light works without issue and the installation was painless. The cross reference info makes it easy to buy with confidence from etrailer, and I will do so again when the need arises.
The fact that this company reaches out to you after a year to check on your satisfaction is exemplary and I appreciate the after the sale service.

Still bright at Night! Flawless product from e-trailer.
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!

Love it the taillight works great!
I replaced a trailer light that was hit and broke in the parking lot. I was happy that we find the exactly match and I was able to change it myself, very easy and quick.
