First of all a great product for the price. After a few rains, let's look at the electrical and lighting. Second, two screws were missing to attach the extension to the frame. 7/16x14! The instructions were more than helpful. After figuring it out, the lower fender under the front bumper had to be removed or cut out (I chose to cut). Installation was pretty easy. You'll also need to know how to connect the battery, install the relay, and route the switch through the firewall or grommet on the driver's front door. After installation, drive at night and with the LED on, it is better than high beam. In general I am satisfied
