Since you have already determined that it is a ground issue (which is almost always the problem) I would try sanding down the area you are installing the clearance light on.

A good ground will have a solid connection to a clean, bare metal surface. If the screws are loose (as you found) or the metal has some paint or debris on it there could be some issues.

If that doesn't work you can also try using a ring terminal like part # DW05737-1 and some 16 Gauge Wire # 16-1-1 to create a better ground.
