Every light in the lineup uses top-bin OSRAM and CREE LEDs rated for 50,000+ hours, reinforced hardware with upgraded bolt threads, and a two-stage gasket redundant waterproofing system.

The ordering process was very efficient

Fast and easy

Fast shipping

The ordering process was very smooth, order processing was very quick, the big fault in the process was the transportation for final delivery.

A+

It seems to work. My reverse lights don't seem to work but I'm going to mess with it more after this storm thats coming in.

Great price and quick delivery. The only issue I had was that I did not receive a shipping confirmation and tracking info. I had to contact customer service and they weren't even clear on shipping info. While I was waiting for a reply, the tire showed up at my house. I received shipping confirmation the day after it arrived.
