Formula-J87 Conversion Wire Harness - 9004 HB1 To 9008 H13 Headlight Adapter Plug & Play

Upgrading your headlights but the plug doesn't match?

This Formula-J87 conversion wire harness is the simple answer.

It's a brand new, plug-and-play adapter that lets you convert from a 9004 (HB1) socket to a 9008 (H13) bulb.

That means you can run modern H13 bulbs in your older vehicle.

It's a set of two harnesses, each with ceramic sockets that can handle the heat.

They're rated for 55 watts and up to 10,000 hours of life.

They're also road legal, CAN bus compatible, and rust-resistant.

Just plug them in, no cutting or splicing.

If you're retrofitting lights, this makes life a whole lot easier.
