Exactly that, plus a tiny amount of bending of the copper strip, solved our problem with all three lights.

I pulled all three overhead lights out yesterday and brought them home for repair.
The passenger light plastic had melted and I had to warm it up to restore a suitable shape for spot light movements.
Not very nice to find that out. :thumbsd:
I bended the copper plates to restore a good electrical contact. I'm not sure how long it will last though.
I ordered LED bulbs from Bulb Town website. I presume they will produce less heat than the tungsten bulbs.

The LED bulbs draw very little current and produce almost no heat. I managed to leave my pilot map light on over a recent weekend trip (from Friday evening until Sunday afternoon) with no noticable effect on the battery. With the stock bulbs, I know (from experience!) my battery would have been dead on Sunday.
