Flickering or blinking lights are usually caused by one of four things:
Loose connections – The plug needs to be secure in the socket. Resistance, even if it is low, can overheat the connection and wires. This is a potential fire hazard, especially if near any flammable materials.
Loose bulb – Check to see that the bulb is secure in its socket. This is a simple task. If the light continues to flicker, there is probably another problem.
Voltage changes – Most homes use 200 amps for the main electrical service. Appliances that need and draw more current will cause flickering of other lights.
Type of light – Fluorescent lights sometimes use an inductive ballast to control the current into the bulb. Disruption of power through the bulb can cause it to flicker
