This thinline light uses four amber LEDs that shine brighter than old bulbs while pulling just 0.051 amps at 12.8V. It’s built to replace incandescent clearance or side marker lights with a cleaner, more efficient setup that you don’t have to worry about burning out. The LEDs last about 50 times longer than traditional bulbs, and since there are no filaments or glass to break, it stays dependable through vibration and weather.
Water intrusion can ruin a trailer light fast, but this one’s sealed up tight. The housing and lens are sonically fused into a single waterproof unit, so it’s completely submersible and safe to use even on boat trailers. That seal keeps the diodes and circuit board protected from moisture and corrosion, so the light keeps working season after season without fogging or shorting out.
When space is limited, the low-profile Thinline Series design fits where bulkier lights can’t. Measuring 4-1/16" long by 1-1/4" wide and only 1-1/8" thick, it mounts cleanly on flat surfaces with a separate bracket (A65B, sold separately). The rectangular shape gives it a modern look, while still meeting DOT P2 standards for use as a clearance or side marker light.
This light’s P2 rating means it projects a 90-degree total beam—45 degrees to either side of center—for strong visibility straight on and from an angle. It’s designed to serve as either a clearance or side marker light depending on how you mount it. Paired correctly, it helps keep your trailer visible at night or in low-light conditions for added safety on the road.
Wiring is simple thanks to the industry-standard plug connection. It accepts either a single-wire setup that grounds through the bracket or a two-wire plug if you prefer a separate ground. That flexibility makes it easy to tie into your existing trailer wiring without cutting or splicing—just plug it in and go.

good looking light and very bright
Great product and fast shipping!
All items look perfect. Just as described. In fact some are the same as on trailer now.
Easy to install (with those bases you have to buy). The click right in. Pretty bright too.

I have to press them back into the bases a bit every now and again but they are still bright and look great. Very pleased.

Fast shipping !!
Very clean fast shipping
Very fast shipping!
Works as advertised. Puts out a lot of light!
THE LIGHTS ARE VERY BRIGHT AND EASY TO INSTALL, I'M VERY HAPPY WITH MY ORDER. MY THIRD TIME ORDERING FROM YOU IN THE LAST MONTH. EVERYTHING HAS BEEN BETTER THAN EXPECTED.
While etrailer's products have been good so far (I have ordered several items lately), what really pleases is their quick and pleasant service. Always easy to deal with, and that makes a difference.
Fast shipping on this order. The lights are a lot brighter than I expected, which is great. Thank you very much. Will do business again.
I replaced all oem lights on my boat trailer with LED's, easy to install and still burning bright today.
Love these lights ! When I leave thr racetrack on Saturday nights everyone stops and stares at my trailer . Better get you some !
My son just started to do metal fabrication. First project is a utility trailer. I'm letting him do the project with very little help on my part. Althought I want him to get the the best product for the bests price and not get ripped off. We found that with your company.The customer service was excellent.
Nice upgrade from the non LED lights on my horse trailer. Love it!
bright, night and day difference between original trailer lights and the LED's!!
Have been great in the weather, dont forget the mounting brackets #A65B
Easy installation and great lighting. Only thing is I wish it was more or a flood light rather than a spot light. But that's just my opinion I also like that moisture doesn't affect them of get in at all.
the lights are very nice (bright) but the bracket housing that they fit in (plastic based) are really not a very good quality. The snaps on each end that holds the light are not all molded the same and I had one defective one that would not allow the light to snap in therefore the first bump i hit the light itself flew out going down the road and was lost. can't afford to keep replacing lights that simply fall out.
I can say enough about item,it was easy to install and it made my enclosed car trailer look outstanding. I would highly recommend these replacement lights to anyone who would like to upgrade the look of their trailer.
Very pleased with the thin Miro- flex side markers. I put them on my 2001 dodge dually and man are they bright. I only wish they offered them in 2 1/2 too. But over all they are well worth buying if your looking for good looking lights on or off.
Finished ProductThe 6 Amber LED's with clear lenses
are now on my pickup. The 20 amber and red clears will outfit my trailer. I
have attached a pic of the rear of my homesteader ez rider (which mainly
hauls my atv)
Here is a picture of these in use on the front of my truck, its an unorthodox mounting place and its supposed to be used on a trailer but I really love these things and I have installed them onto another guys truck as well
