H4 Halogen Headlight Conversion w/Heavy Duty Wiring Harness Kit, 1966-78 Ford Bronco & 1956-78 Ford Truck

Early Bronco halogen headlight kit with heavy-duty headlamp wiring harness & relays. This headlight kit is street legal in all 50 states.  Our high-quality Bronco headlights feature an aluminum die-cast housing with a protective finish coating to prevent corrosion of the headlamp housing. This headlight kit provides a brighter light than the stock Ford Bronco headlights, resulting in greater visibility, distance, and clarity. The strong, semi-hardened crystal clear glass lens and inner reflective mirror finish of these headlights offer a great look and a more clear light. This headlight kit includes high-efficiency white halogen 12V 60/55 watt replaceable bulbs. Our early headlights are DOT and SAE approved.  To ensure optimum light output and long lasting performance, our exclusive kit also includes our heavy duty headlight wiring harness. This harness upgrades your stock headlight wiring harness for maximum light output and stability. This is a necessity when adding high output bulbs to take advantage of the extra light output.  NOTE: Our headlight harness includes a pre-installed diode that allows the high and low beams to emit light at the same time when the bright head beams are turned on. Should you need to disable this feature, simply remove the diode from the wiring harness.
