Formula-J87 9006 HB4 Fog Light Relay Wire Harness With Ceramic Connectors - 30A, 12V

So, you're upgrading your fog lights or maybe they're not working right?

This Formula-J87 relay wire harness is what you need.

It's designed for 9006 / HB4 bulbs, which are common in fog lights and some headlights.

The big deal here is the ceramic connectors—they handle high heat much better than plastic, so they won't melt.

The harness itself is rated for 30 amps at 12 volts.

It helps fix voltage drop and can increase light output by sending full power directly to the bulbs.

It's a universal fit, so it should work in most applications with those bulb types.

It's also CANbus compatible, which helps avoid error messages in newer cars.

Comes with a 1-year warranty.

A solid, heavy-duty harness for a reliable connection and brighter lights.
