Old incandescent bulbs fade fast, but this thinline light keeps shining. Its three white LEDs shine through an amber lens for efficient, long-life operation that’s up to 50 times longer than traditional bulbs. With only a 0.048-amp draw at 12.8V, it’s bright and dependable while keeping power demands low. No filaments to break, no bulbs to replace—just consistent illumination every time you tow.
Water intrusion can ruin a light fast, but not this one. The polycarbonate housing and lens are sonically sealed into one waterproof unit that’s fully submersible. Whether your trailer is exposed to heavy rain or goes beneath the surface at the ramp, the diodes and wiring stay dry and protected. It’s built for reliability in wet or harsh conditions.
Tight mounting spots don’t mean you have to compromise on lighting. Measuring just 3-15/16" long, 1-1/4" wide, and 7/8" thick, this low-profile thinline series light tucks neatly along surfaces without sticking out. It surface mounts with a bracket (A65B – sold separately) and accepts standard 1-prong or 2-prong plugs for quick hookups.
For dependable performance you can trust on the road, this light is DOT compliant and P2 rated. Its beam projects at a 45-degree angle on each side of centerline, covering a total of 90 degrees—ideal for use as either a clearance or side marker light when properly mounted. That means it meets visibility requirements where it matters most.
Every part of this light is made to handle real-world use. The tough polycarbonate housing resists impact, cracks, and wear from UV exposure. The amber lens stays clear and bright over time, ensuring your trailer lights remain visible trip after trip without fading or fogging.

Replaces OEM perfectly. Good
First of all, the part I needed was in stock and was shipped promptly. When I received it, it was easy to install and it worked perfectly! Crossed off my to-do list!
Quality product, still working great to this day. They have endured some unfavorable conditions along the way.
Second order from this company. Once again, great service, fast delivery and a
quality product.
These lights are the best because change out is soooo easy and the initial ones lasted 9 years. They are removed with a small flat head screw driver and you snap in the new one. Great product
The CSR Terri was awesome!
I will continue to utilize this site for all my trailer needs.
My old lights had faded badly and the new ones are bright and clear. Improved the look of my enclosed car hauler.
The lights and bases were exactly what we were looking for to convert from the old style to the new snap-in type.
Product was exactly as stated on their website and delivery time was great. No complaints at all.
Mounted these on my boat trailer and these are bright and easy to mount with the A65PB bracket. Have not submersed them yet so I can not comment on how well sealed the LEDs are. Ordered on a Saturday evening, received on the following Wednesday.
These have been on my box trailer for 1 year now. Still working great. For the price these can’t be beat. I will buy again when needed. Very good product. And a great company to deal with.
Great replacement for old faded bulb style lights.
Mounted amber and red light on the side marker on our trailer
Big improvement over the old bulb style.
I like dealing with etrailer corporation. You get exactly what you ordered. It arrives quickly. And I’ve never found anything that didn’t work out exactly what way is they said it would
Excellent product. If buying for the first time don’t forget to buy the mounting bracket!
Profesional and friendly customer service. I had a great experience ordering from etrailer.
My order came quickly and was complete. Lights installed quickly.

No more blown fuses. Quick and easy to install. Brighter than the original. I am extremely happy with them!
The led trailer clearance lights were a perfect replacement. They just snapped into place.
Ordered new LED marker lights for my trailer, they were exact fit & work great. Would buy from etrailer again in a heartbeat.
Great products and fast delivery
Needed to get trailer inspected. I have a hard time sometimes finding these light assemblies in my local area. Had to replace one assembly and base as ground contact was corroded away. Order arrived as promised and trailer is ready to go now. Thinking about ordering connection box and trailer cable assembly to make connections easier. Wires on trailers do not always match standard wiring colors. Need to label connections box with functions as colors do not always match.
Quality product!
The LEDs light up brightly. They're brighter than i expected! I bought enough to change out all my trailer lights, it worked out well. So far they've been through some extreme weather. I've used the trailer in heavy rain, high heat, through winter and freezing temps, and many washes. They haven't leaked and lenses still look great. It's only been a year and I'm hoping these will last many many more.
Hard to find replacement lights. Amazing communication and fast shipping highly recommend
The replacement lights that I ordered for my Haulmark trailer were an exact fit. Your website is easy to use and your service in delivery is quick! I will continue to use etrailer.com for future needs as they arise.

After one year, the replacement parts have performed perfectly. The LED clearance lights and tail lights are bright which is definitely an added safety feature on the highways and around town. Great product, easy to use website and quick response to deliver purchased products.
I have a 2006 Brenderup Horse Trailer. My side markers were destroyed by the sun and intermittently working. I found what I thought would be an exact match on etrailer after looking high and low on the internet everywhere else. Normally I'd get an out of stock message. etrailer's model 19 lamps worked perfectly. Best thing was I did not have to buy and replace the base (also hard to find online). I just had to snap the old ones out and snap these in. Now our trailer and horses are as safe as can be, barring unsafe and stupid drivers on the road, who seem to be unsafe and stupid no matter whether or not my lights are working. LOL. Just sayin.

Unsafe and stupid drivers is putting it nicely, if you ask me! I'd love to see a photo of your horse trailer [maybe with a horse in it too?] if you ever feel like sending one in ;)
