What is BULB SOCKET?
Bulb Socket is the mechanical device that physically holds the light bulb in position, and, provides the electrical connection to the light bulb.
Usually the socket is designed to make a temporary hold on the light bulb to allow for future light bulb replacement.
Make certain the socket contacts and light bulb contacts are clean so they provide solid electrical connection.
Replace socket or bulb if poor connection is made.
