Spot on Replacement

I recently purchased a 2011 Forest River Work and Play toy hauler and needed to replace a replacement marker light as I wanted to match the factory marker lights. I looked for Months and found them here , great price and fast shipping. Thanks for having what I needed at a reasonable price.

Plenty bright at night!

I have been restoring my wife's 2-horse Sundowner trailer with new floorboards, new pigtail, new 12v battery and all new LED lighting. I wanted to match the footprint of the OEM lights which these did. The only real issue was these have a different bolt pattern. Wasn't a huge deal but I did need to drill three more holes as NONE of them lined up correctly. I used blind aluminum rivets to install the base plate as those are easy to drill out and I didn't risk a sharp screw chaffing wiring.These look SHARP at night! Very nice and bright!! We'll see about longevity but so far, no complaints. Well worth the price!
