Lights are bright! I like the combination flood/spot pattern for a great general purpose beam of light that seriously turns night into day! Housing is rugged aluminum and should hold up well. Included wiring, relay and switch was sufficient and great to have if you want to control all the lights with one switch. If you want to control them independently, plan on another relay, switch and more wire. If you are good at electrical wiring, you can get creative with the included 3 wire harness and pick up a low current 12v and ground from within the cabin of your vehicle to run the switch backlight and trigger voltage to the relays without having to run an independent wire through the firewall.Now for what I didn’t like. I was not impressed with how these lights mount to the adjustable bracket. They lock the light in position well enough, but the nut is preinstalled in a track on the light and is easily stripped! Tighten with caution. It doesn’t take much to lock the position in. Just tighten until the light doesn’t move.
