H4 Headlight Relay Wiring Harness Kit – Ceramic Socket Plug 4-Headlamp System

If your old headlight wiring is crusty and your lights are dim, or if you're doing a full custom build, this harness is a lifesaver.

It's from PROSCAN AUTOMOTIVE, and it's a universal fit, so it'll work on pretty much whatever you're tinkering with.

The kit includes everything you need to wire up a 4-headlamp system with H4 bulbs.

The best part?

It uses ceramic sockets, which handle heat way better than the old plastic ones that melt.

It's a relay setup, so your lights get full power straight from the battery, making them brighter.

Comes with a 6-month warranty, just in case.

Brand new, ready to install.

If your lights are weak, this is the fix.
