> The whitish film is tungston that burned up when it contacted the air. Basically it should like you just blew a bulb. It happens, sometimes violently sometime they jsut get really dim. High wattage bulbs have thinnner filiments and jsut don't last as long as a regular bulb. And, yes, I'd try getting those shards out.

Another thing I may note.....Don't change your headlight bulbs at the
same time. Every time I've done this I've found that the bulbs burn out
within 1 hour of each other. So, you may start with two new ones, but
then after a few weeks, swap a new one in to one side and keep the other
as a spare.
