Replacing Headlight Capsule in '94 Exp

New to the boards here and seems pretty informative. I recently bought my gf a 1994 Explorer and also bought new headlight capsules. (Old ones were wasted and have connections so why not!?!?)

I need to know hot to go about getting the capsules out. Can anyone point me to a how to section so I don't have to spend $25 on a manual? thanks in advance
