Hello and welcome to Just Answer. My name is ***** ***** I will be happy to assist you with your electrical question.

1) Flickering light bulbs typically indicate a loose connection. Either a loose wire splice connection or the light bulb is not making good contact within the light socket.

2) I suggest to temporarily turn the circuit breaker to the OFF position. Then look inside the light bulb socket and see if the middle tab where the tip of the light bulb is seated against is pushed down. If the tab is pushed downward, get a plastic knife or something that is plastic or wooden and slightly pull the tab upwards so the bulb can make proper contact.

3) If the light socket metal tab is not the cause of the problem, then you have a loose wire connection and the splices at the fan or the wall switch terminations (if applicable) will need to be checked.

4) What type of light bulbs? Incandescent or CFL or LED or Halogen bulbs?

5) Do you have a wall switch? If so, is it a dimmer switch?

1) Check the light bulb socket tab and the splices to the fan light fixture.

2) If the light bulb is constantly flickering and you have an AC voltmeter available, this can confirm if a loose or poor connection.

the blues are flashing not flickering
Expert:  Kevin replied 1 year ago.

Flashing and Flickering are basically the same thing. The lighting filament is going ON & OFF. Flashing is just a faster rate than flickering.

Check the light socket tab and the wire splices. Let me know how you make out and we can take it from there..........Thanks..........Kevin:)

Shown in the picture below is where the middle brass tab is located on a standard Edison based light bulb socket.

1) What is the wattage rating of the light and the light bulb wattage that you are using? How many light bulbs?
