I have found no water exposure and the bulb is safely held in place not loose when I pull it out, but the bulb itself is shattered. I replaced it 2 months ago and two months before that
Why does the passenger headlight keep shattering on 1996 Dodge Dakota
poss to much voltage at bulb
Next time do not touch the glass globe on the new bulb as oil from your skin will shorten bulb life.
