I do a lot of night time off-roading, so I needed a good set of auxiliary lights. I chose the Piaa 520 driving lights. My only beef with them is they are amber colored, which makes things harder to see. Oh well, they look great and are pretty bright. Since I have no brush guard or lamp brackets, or have the desire to have one, I had to drill 2 small holes in my bumper to mount the lights. At first I was not so crazy about drilling into the bumper, but I thought what the heck. I first figured out where exactly I wanted the lights to be by holding up the lights in the proposed position on my bumper. Then I marked the proximate position. Then I got a ruler and measured equal distance from left to right to make sure they were dead center. Then I marked the spot with some electrical tape and marked the exact spot with magic marker. Then I measured about 3 more times to make sure I was right. I wouldn't want to have some goofy looking crooked lights on my bumper. I wanted them to look as good as possible. After making sure everything was right. I got my special metal drill bit and very carefully drilled a clean hole. After drilling I cleaned out all the metal shavings with a rag and then sprayed the holes with WD-40 to make sure they will not rust. I will have to periodically check them for rust so I don't have to replace the bumper anytime soon. Then I bolted them up. They came with all the wiring to get the job done. I mounted the relay under the hood and connected it to the battery. Then I ran the wires for the switch through the firewall opening used for my amp and inverter. I wire the switch's power in the fuse box. I installed the switch where the blank hole from where the switch for the factory electric locker SHOULD be, but isn't.
