94 F150. If the tuck sits out in a hard rain, I get a lapful of water when I make a left turn. One day I plan to pull the headliner and either remove them and weld up the holes, or figure out a way to seal them better. I've tried sealing them with a layer of tub caulk under the lights, but the leak still comes back after a few months.
At one point in it's life, my truck had a plow- I think that's why the lights were installed.
After living through many vehicles with aftermarket sunroofs, I am dead against drilling any holes in the roof
