how do you replace dim lights in a 1995 pontiac grand prix? do you have to replace the whole kit or the bulbs both are out?

Yah. Just the bulbs. My GTP has plastic covers that open just above the back of the light. Should be able to pop the wire off and twist the light out. Take your time with the locking tabs try not to break them. For the most part I change both bulbs at the same time and keep the one good one as a spare.
