If your recessed light bulb is stuck, don't panic! There are a few easy ways to unscrew it and get it out.
First, try using a pair of needle-nose pliers. Gently grip the base of the bulb with the pliers and twist counterclockwise. If the bulb is still stuck, try using a putty knife or flathead screwdriver. Insert the blade into the gap between the housing and the trim and gently pry outward. This should loosen the bulb enough to unscrew it by hand.
If neither of these methods work, you may need to cut through the sealant around the housing with a utility knife. Be careful not to damage any wires or other components inside. Once you've cut through the sealant, you should be able to remove the housing and access the bulb from behind.
Finally, if all else fails, you can always call an electrician to come and take care of it for you!
