This harness is designed to provide your quad H-4 headlight system with consistent battery voltage.  Amperage is sourced directly from the battery instead of the headlight switch.  This results in brighter headlight beams.

This kit includes:

1. Two 40 Amp weatherproof relays
2. Two weatherproof relay bases with harness
3. Mating connectors to factory headlights and harness
4. Mounting hardware
