Most light fixtures use bayonet caps. To remove a bayonet light bulb, hold the bulb housing firmly, push the bulb into the housing and twist in an anti-clockwise direction. Withdraw the bulb. For screw cap bulbs, see step 5.

Line up the bayonet studs on the light bulb with the slots in the bulb housing. The studs are the little bars that project from the side of the bulb on the metal base. Push the bulb into the housing and then twist in a clockwise direction. You will feel resistance after a turn of about 30 degrees, and you can then release the bulb slowly to engage the holding mechanism.
