    •H4 LED Headlight Brightness Intensifier Wiring Harness-It makes the high/low lights brighter of your car!

     

    •CONVERSION MADE EASY - Save time, money, and headache by utilizing this wiring harness to convert a ground switched headlight system (2 toggled grounds + 1 constant hot) to a positive switched headlight system (2 toggled hots + 1 constant ground).

     

    • NO LOW-QUALITY PARTS HERE - Designed with two sturdy relays, high-temperature ceramic headlight sockets, and heat-resistant polycarbonate wire loom. This harness is built to last.

     

    • THE WAY IT SHOULD BE - We set out to build a harness that would install with as little effort as possible. The result? A conversion harness that takes only minutes to install and works every time.

     

    • PRESERVE YOUR STOCK COMPONENTS - The beauty of this conversion harness is that you don't need to cut into your stock wiring harness. This dramatically reduces the install time, and if you need to, even makes the process completely reversible.
