Biggest change I made to my truck was to power the headlights through a couple relays and run 12 gauge wire to them. Made a huge difference, I even used a small diode to keep the lows on with the high beams to help fill in right in front of the truck. Just be nice to oncoming drivers as there is a lot of light with highs and lows on. I was worried about overheating of the bulb at first, but after 4 years haven't popped a bulb yet. <!-- google_ad_section_end --> <!-- / message --><!-- sig -->
