Modern style headlights
I would HIGHLY recommend setting up the relays for your headlights. Whether you buy a harness/relay kit, or make your own (it isn't that hard), you will see a MAJOR difference. That upgrade provides the voltage necessary to power your headlights instead of losing a significant amount of power with the factory wiring (which is undersized and passes through the firewall, the headlamp switch and back out to your lights). This has been discussed many times on this list and there are some good recommendations on how to complete it if you do the search. If you can't see purchasing the Cibie's headlights that Dan recommends, then get a good quality set of halogen headlights. I know I use the GE heavy duty sealed beams. With the upgrade of relays and halogens, they put out as much if not more light then my newer cars.
