I had to replace one of my fog bulbs (not working straight off the dealer lot... poor ). While squeezing my hand and the bulb through that underside plastic guard, I unwittingly touched the bulb surface with my bare hands. I understand that fingerprint oils can cause premature failure of the bulb. Should I try to remove the bulb and wipe off the surface? Am I out of luck? Or would it have blown by now if it was going too? It's been in for about 5 days, with plenty of running time and no problems yet.
I've only lost one so far, and it was replaced at the dealer when I went for a host of maintenance work. However, mine has serious condensation issues, and I'm sure the water content had more to do with it then any man-handling.
That in mind, what is the best way to get the water vapour and condensate out of the fog lamp? Drill a weep hole? If so...where?
Thanks for the tips... mine fog light housing (at least for the one I changed) looks like it ALREADY had a small hole drilled in the bottom. I thought it was stock, but I guess the previous owner or dealer did that at some point.
