Clearance Light Leaks?

[Jim A]

I finally got around to replacing my front clearance lights today. One has been leaking slightly. When I removed the first light, I found two cracks in the fiberglass in the corner of the recess hole. Neither was long enough to be beyond the clearance light seal. When I removed the second one, there were three radial cracks around the mounting screw hole. These cracks were longer, and could possibly be responsible for a small leak. I still need to replace the other three tomorrow. Not sure what else I might find!

So if you are seeing any leaks in this area, this might be another problem to look for. I would like to think that only my coach has this, but I know better! It looks like somebody used the old rule of thumb: Tighten until it strips, then back off 1/4 turn.

4 out of 5 of my front clearance lites leaked and the light sockets were so corroded i had to replace everything. when you install the new lights go around everyone with caulk so they donot leak any more. someone else may know how to seal the cracks?
