To Replace Bulbs:
1. Unplug the Christmas lights.
*****Make sure the light string is unplugged from the wall and any other
light strings before you start working on it.
2. Remove each of the blown-out Christmas light bulbs. Use your thumb
and index finger to delicately put pressure on each of the broken light's
plastic jacket, to remove the bulb(s) from the bulb base.

3. Make sure the two copper wires are completely aligned with the bulb's
base and the copper contact points inside the base. Now, insert the
replacement bulb into the old bulb's socket.
