You cannot beat the price!

I was kind of skeptical because of the price but for $50 it more than exceded my expectations! Great buy! I am considering buying a second one for my other vehicle, easy to install with the wiring harness.

Fiona Robel
Insanely bright and easy to install

This is on a 2015 RAM 1500. I already had a light bar and a bull bar. My old light bar was just getting dim. I swapped it out for this new one. Holy moly this thing is bright. Don’t look at it for too long. I have a headache. Wear sunglasses. I want to buy another one.
