I live in Ontario so delivery was a little slow...but Everything was perfect!


Excellent product great update for older incandescent lights


Only issue was the plug on the end did not fit my FeatherLite trailer plug-in. It could have been a little sturdier.

Works good for 1998 featherlite trailer replacement. I spliced them in due to quick disconnect being wrong size.


In general, I am very pleased with the LED marker lights I ordered. One bit of advice, there is a "zero clearance" fit between the light itself and the mounting base. Therefore, the only screw that will work must be a tapered head which sits, fully recessed, within the mounting holes. The lights did not come with any mounting screws, so you must source your own.


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.


I have six of these amber leds on my boat trailer now, adding two red leds rear facing on fender. My Trailer has plenty of bling and everyone sees it coming and going... Etrailer service is always great, shipping prompt and pricing is the best I have found.


Simple install, retrofit to old boat trailer. Drilled two hole, fastened with rivets, installed lights and wired. Total job for both sides took less than 30 minutes. Used
MCL63AB Thin line LED lights. Very bright!!


I have been in trucking for sixteen years and these bases and light combination have held up the best in all weather conditions.These are my go to lights.


Worked great on my 2008 and 2006 Feather-Lite trailers.

Phil S.


Working great, no issues


Good replacement for Featherlite trailer. Could use a larger connector on the end but I was just using spices so I cut it off.


Easy installation.



Still working great after a year. Every once in a while I have to press the lights back into the mounts a bit but it isnt really an issue.


I have not assembled the trailer yet, but the quality of the parts
is good, delivery was quick and the price was great due to the
free shipping. So far my favorite place to buy trailer parts.


Single wire mount is the same as my featherlite trailer


Great stuff. I just replaced old one on trailer today. It went smooth.


Very nice. Well built. Good quality. Would buy again. This company is awesome to deal with!


Great product, worked great!


Great light
