This video will show you how to wire a Painless Performance headlight relay into your OBS Chevy / GMC truck or Tahoe to keep the low beams on when you run the high beam lights for much better light coverage in night driving conditions. more. If your headlights suddenly seem too high, too low, or uneven, you likely need to adjust the beam pattern on your headlights. In many cases, poor headlight aim comes from extra weight in the rear of the vehicle. For example, a loaded trunk, hunting gear, tools, or a trailer can push the back end. When we want to replace and upgrade our car headlights, we will pay attention to their brightness and beam pattern. But there is one important factor that is often overlooked - the cutoff line. You can. A blown out low beam bulb can make it difficult to see at night and driving with your high beams on all the time can make it difficult for other drivers to see. Fortunately, fixing a bad low beam is a straight forward process in the majority of vehicles that can be done by most people without just. This DIY will explain how to hookup your DRL's to stay on with your low beams WITHOUT running a switch in the cab. One 30 amp max fuse holder 5. Length of assorted color 14-16 guage wire 6.
