Heavy Duty Headlight Conversion Harness w/Relays, each
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.
