Performance H4 Halogen Headlight Harness

For maximum power from your headlights you must have the shortest possible distance between the power source and the bulbs. Some factory headlight wiring is not designed to handle high power Halogen Headlights, especially when upgrading to a higher wattage. Running the power through the switch is even worse. Resistance in small gauge wire or in the switch will lower the output at the lamp. Be Safe! Painless Performance headlight harnesses draw power directly from the battery, through a relay, to the headlights, providing full power to your H4 conversion headlights or Halogen sealed beams. They are made of TXL high temp wire, weather resistant 30 AMP fuse, and two 40 AMP weather resistant relays capable of handling up to 150 watts.
