I tried searching for a thread I saw a while ago, but couldn't find it. My bro's headlamp had moisture sitting in there far to long and it messed up the bulb. We replaced the bulb and resealed the lamp but the headlamp is now kinda foggy and dull (no moisture, just really yellow looking). It looks like it needs polishing. We plan on taking it apart again but we were hoping some one knew of a product that would clear out that foggy headlamp? Or do ya'll think we need to just buy a new headlamp?
