Features to know about

Reliable Lighting for 24V Systems: Bright Amber LED Performance

If you’re running a 24-volt setup and want dependable visibility, this Optronics LED clearance or side marker light is made for it. It’s fully compatible with 24V DC systems and will even operate on 12V with reduced output. The six bright white LEDs behind the amber lens deliver strong illumination with a clean, efficient glow that draws only 0.057 amps at 12.8V. It’s a simple way to get modern LED brightness without adding strain to your electrical system.

Built to Handle Water Exposure: Sonically Sealed and Submersible

Water intrusion can ruin trailer lights fast, but this one is ready for it. The housing and lens are sonically sealed together into a single waterproof unit that’s fully submersible. Whether it’s rain, road spray, or launching at the ramp, water can’t get in to damage the diodes or circuit board. That sealed design keeps the light performing reliably season after season.

Simple Installation Anywhere: Compact Surface-Mount Design

Mounting is straightforward thanks to the rectangular surface-mount design. Measuring 4" long by 1" wide and 1-3/16" thick, it fits neatly on most flat surfaces without extra brackets or plates. The center-to-center hole spacing is 3", so it lines up easily during install. The two-wire design—power lead and ground—keeps wiring simple and clean.

Consistent Visibility and Compliance: P2-Rated Amber Lens

Safety lighting isn’t just about brightness—it’s about visibility angles too. This P2-rated light provides a 90-degree beam pattern (45 degrees to either side of centerline), making it ideal for use as a clearance light or a side marker when properly mounted. With its durable amber polycarbonate lens and housing, it meets DOT standards while helping others clearly see your trailer’s position in low light or at night.

Long-Lasting Efficiency: No Bulbs to Replace

Forget about replacing burnt bulbs or dealing with fragile filaments. The solid-state LED design lasts up to 50 times longer than incandescent options while using far less power. Combined with its durable polycarbonate housing and lifetime LED warranty, this light is a dependable, low-maintenance upgrade that just keeps working trip after trip.

Super fast shipping. Product was as described and works perfectly as replacements on my motorhome. Very happy with this experience.



by:

I bought the led lights over a year ago and even with MI winters and all the road salt the are still working perfectly. Great product you won't go wrong buying them.



by:

Ordered the LED trailer pucks. They came really quickly, and the bonus was they already had dielectric grease on the female contacts and ready to install. I was pleasantly surprised.



by:

I thought yall were just trailers , was not aware did boat as well, thanks deliver in great shape



by:

The lights went on easy with one positive wire and ground. Being led makes it brighter than my old lights



by:

Had trouble tracking these specific lights down online. I have bought a few things from etrailer before and they always deliver exactly as advertised. These are a direct replacement for the lights that I had which seemed impossible to find!



by:

The light works excellent. Unfortunately after I took the old one off I realized that the original was never wired up correctly from the factory lol. New light is much brighter so I might go ahead and replace the other two. Received very quickly.



by:

These Optronic LED lites were exactly what I was looking for my boat trailer. Easy install and very bright. Good product and quick shipping. I highly recommend this company.

Etrailer had plenty of choices and made them easy to sort through. Prices were reasonable and they shipped the next day. Great company. I'll use them again



by:

Product exactly as described with fast shipping! Great supplier!



by:

We were looking for lights that we could use on a trailer so it could be towed by a truck with either a 12 or 24 volt electrical system. These lights answer that need. They appear to be well made and are very bright.



by:

I love the B&W gooseneck ball and hitch. There are so may different ways to setup from 5th wheel to gooseneck styles. I sold the truck that had the B&W hitch and regret not getting it in my new truck. If I could afford another new hitch it would be B&W for sure.
