mark, bill, chris, patrick, thanks for replying guys... i think i'm leaning towards leaving the headlight as is and once i move (and have oodles of time on my hands for up to 3 months while i can't work - oooo, lookie the stuff that's finally going to get done!) maybe take it out if i continue to have problems and try and fix the seal myself.
it's just so weird that the few times i've washed the car both before and after the incident, i didn't notice a thing - and i would definitely notice something like that. guess i'll make an appointment to get the 3m put on this headlight so it's protected to and she'll be good to go.
oh, btw - i know the hi-beam bulbs have that rubber boot on them to prevent moisture from getting into the housing; do the low beam bulbs have the same thing? my car doesn't that i can ever recall, a buddy's car doesn't, but when i was picking up a couple parts at a different dealership and asked them, they said it should and printed out a diagram showing this (and yes, it was a P5 headlight)... i'm confused.
