Does anyone have information on installing running/clearance lights for an H3?
If anyone has them installed what type of lights were used and what wires are connected to what?

 

I'm assuming you are talking about the Orange Roof Marker Lights? If so, they are currently not available due to a design flaw that is allowing air to pass underneath the piece. They should be available again by the end of the year.

As far as installation. The Roof Marker Lights come in a kit form from the dealer with all the wiring and instructions you need to install them.
