Allow the current bulb to cool to avoid burning yourself. Remove the old bulb. For bayonet mounts, grab the bulb gently and push upwards. Slowly turn the bulb anticlockwise to release it from the socket. Replace with your new B22 bulb. Do this by pushing the replacement bulb into the socket and turning it clockwise until it locks in place. You should ensure the bulbs have the same wattage and avoid putting your fingers into the socket. After this, you can restore the power to test if the light turns on.
