We have two bulbs in our house that need replacing. They appear to be PAR38 bulbs.
The bulbs are both in recessed sockets. There is not enough space between the bulb and the well to get fingers around. The bulbs are in too firmly to budge with what little torque we can exert from the face. Obviously, we don't want to try anything that would break them.
A Google search for "bulb changer" yields some promising results, but I figured I'd ask some humans to be sure.

Take a piece of duct tape and wrap it in the shape of an "O", with the sticky side of the tape on the outside. Stick the loop of tape to the face of the light bulb such that it is secure. Put your hand (four fingers) inside the loop and twist counterclockwise to loosen the bulb.
