When I needed to change my AMPS bulb, I noticed that it [bulb] was glued in, which nobody warned me about. Perhaps because nobody else seems to have it like that.
When I pulled it out, the glass shattered. I had to empty the big pieces, dig out the leftover glue and use a compressor to blow out the tiny bits.
If I were you, check to see if its glued. If not, pull. If it is, I would try to work something thin and sharp to cut the glue first. It'll be worth it.
