How do i change a headlight bulb (right side) on a 2001 cadillac?

there's no space behind it to get your hand in, and there's no screws holding the lens on! thanks for any help.How do i change a headlight bulb (right side) on a 2001 cadillac?its actually really easy. all you have to do is pop the bulb out of its socket, its usually held in with a pressure ring that you just squeeze to re lease or twist out to unlock it, then you pull the bulb out of the socket and replace it then put the new bulb in the same way you took it out.

good luck
