New Heavy Duty Headlight Wiring Harness w/Relays. This Heavy Duty Headlight 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 brights are turned on. Should you need to disable this feature, simply remove the diode from the wiring harness.

The HD wiring harness for the headlights went in very nicely and seems to really help with the stock headlights.

Fantastic product, works great with the stock wiring harness, plug and play. Helps keep stress off the headlight switch so that it won't burn out so easily. Also makes those stock halogens way brighter! High quality and plenty of cable for routing, even in my pickup. Works great in my 72' F100, so it will work with pickups, don't let the Bronco title fool you. Love your harnesses, keep up the good work.
