I believe you can put the headlights in an oven until the sealant melts and the glass will come off.

When you say blue bulbs, are they xenon bulbs, or bulbs that produce a very blue looking light output?

I would reccomend not doing the whole blue light thing. 1. Your just asking to get a ticket since that is illegal. 2. They are ugly. 3. Taking out the reflector is also illegal, but probably not enforced very often.

Stay stock, or upgrade your bulbs to something decent like silverstars.
