when i left for my lunch at work, i saw in the reflection of a building my passenger side headlight went out (i have eurolite headlights) so i was like "aw that sucks" so as i continue home i pull up behind a car and look in the reflection again and BOTH headlights are out, so now i'm like "WTF!!?!?!" so when i get home i look at passenger side bulb (the one that went out first), its blown then i look at the other and it blew up to pieces! wtf happened? its not like it got a heavy dose of watts or something cuz arent the headlights like independent from each other? so now i got all these little pieces of bulb stuck in my headlight that i have to figure out how to get out.

any ideas on why it did that?
