This light swaps out fragile bulbs for three long-lasting LEDs that shine bright while using less power. At 12.8V, it only draws 0.051 amps, so you get high visibility without putting a strain on your wiring. The LEDs last up to 50 times longer than incandescent bulbs, meaning no filaments to break and no bulbs to replace. It’s a clean, efficient upgrade that keeps your trailer safely lit.
Moisture is no match for this light’s construction. The lens and housing are sonically sealed into a single waterproof unit that’s submersible, keeping out water that can corrode wiring or fry diodes. Whether you’re on wet roads or loading at the ramp, the sealed design keeps the LEDs protected and working reliably trip after trip.
Installing this light couldn’t be easier. It mounts with a single stainless steel stud that doubles as the ground, so there’s only one wire to connect for power. No extra grounding wires or complicated hookups—just secure it with the stud and you’re done. The compact 2-1/8" long by 1-1/8" wide size tucks neatly onto the surface where you need it most.
Safety comes from being seen, and this P2-rated light delivers a focused 90-degree total beam spread—45 degrees to each side of centerline—for solid visibility straight on or at an angle. That makes it perfect as either a clearance light or a side marker light when mounted correctly. It keeps your trailer visible in low light so everyone on the road knows where you are.
The red polycarbonate lens and housing aren’t just for looks—they’re built to handle bumps, vibration, and outdoor exposure without cracking or fading. It’s a rugged setup that holds up over time while still looking sharp. Once mounted, it’s one less part you’ll have to worry about replacing anytime soon.

Excellent replacement for a damaged light on my trailer. Now LED lights are an upgrade from original. Probably not feasible given a variety of applications, but a plug in tip would avoid the need for splicing the wire. Overall, a good product and easy replacement installation.
Red marker light
Replaced the boat trailer lights and bunk boards, fenders and added a set of guide post and rachet straps, now my boat trailer lights up like achristmas tree and has never been easer to launch and load, thanks etrailer, great products fast shipping and great customer service, accidently ordered the wrong size fenders and the folks at etrailer got me the right ones, fast, easy and couldn't have had a better experience, thanks again
The side marker lights were exactly as described. The look. fit, and install couldn't have been better.
Works great! Need to get 3 more.

working fine.
Exactly the replacement LED marker light we needed and Etrailer.com was the only place I could find it. Local stores and even online stores did not have this item, only Etrailer.com. It arrived quickly and intact.
Great LED clearance lights, replaced old ones on my boat trailer. These are far
brighter, and more dependable than the old bulbs that rarely worked. Very happy with theses lights

Still going strong, no checking bulbs or connectors this season, all my LEDs are working great, hook up and go!
Another bonus Optronics has a product lifetime warranty that they actually honor. Good company to do business with.
Works great. I need to order more because now one side looks better than the other!
Fit perfect
Correct product,quick shipping.

Just what I was looking for

Good service, good product.
I’m using these on a boat trailer that goes into the ocean. The bulbs are sealed and the backer plate is stainless but the bolt is zinc. I swapped to a stainless nylock nut but a stainless bolt doesn’t fit the back plate.
Work as expected absolutely no problems
Difficult to find but not on etrailer. Fits the trailer as it should. The other clearance lights would require cutting out larger holes to fit the wires.
Smaller than I needed. I'm sure they fu nction
The one year later the parts are still working well
Delight seemed very well made. They’re very bright. I’m very happy with my purchase.
Received a large bolt. I ordered a trailer side marker light.
Excellent product- exactly what I was looking for. My only recommendation is don’t use USPS - the delivery date was late by days.
After a year of use I have had zero issues with my LED trailer lights. They are mounted on a farm trailer so never submerged like boat trailer lights would have been.
The lights are bright and have performed up to expectations. So much better than the older incandescents.
Very pleased.
Great looking product. Very well made. Perfect fit.
Great shopping experience and fast shipping.
