Are your headlamps a bit dim, or would you like to install halogen beams without rewiring the entire vehicle? American Autowire headlight enhancement relay kits supply 12 V directly to the headlights, while existing wiring controls the relays. This upgrade would also allow for the use of modern halogen bulbs—which produce significantly more viewable light than incandescent. The existing lo/hi beam wires from the dimmer switch will activate the relays. When it gets tough to see where you're going, an American Autowire headlight enhancement relay kit is the answer.
