Headlight Upgrade, H4 Harness, 1975-88 GM's

High power headlight upgrade

Increase visibility while maintaining original appearance

Easily upgrade your standard halogen 45/55 watt headlights to a more modern and powerful 55/60 watt headlight system with this all-inclusive kit. The four headlights included have a glass lens which keeps the stock appearance and fit, no modification to the headlight housing are necessary. The included plug-and-play harness re-routes power directly from your battery to your new headlights using two 80 amp relays, an in-line fuse, and the proper connectors, eliminating concerns from running higher amperage through the original headlight switch. The harness can also be used to upgrade to even higher wattage halogen bulbs (up to 80 watts) if preferred. The 55/60 watt H4 upgrade bulbs can be purchased individually as replacements. Satisfaction guaranteed!
