Hi I installed a fan light in my bedroom. The wiring diagram was simple just add an extra wire. Tap into the live wire before the switch and run it out of the fan control into the port provided on the fan. It all works fine. However all night the led light flashes. About every 5 minutes even though it's turned off. What is wrong. Tia

    Is the switch for the light a regular switch, or something more sophisticated (like a lit switch, a dimmer, a timer, or a smart-switch)? Feb 11, 2019 at 12:45

The answer likely is get a better bulb.

I couldn’t follow your installation description exactly, but the “fan control” and the bulb are not compatible with each other. The control leaks a little bit of current when it’s “off”, that builds up in the bulb and dissipates with a flash.

Pick a name brand (Phillips, GE, etc) bulb that is labeled as “dimmable” (even if you aren’t dimming). This caliber of bulb quality should solve the problem. The electronics or driver that coverts voltage for the LEDs is just too cheaply/poorly made in the bulb that you have, it’s fine for circuits with physical switches, your “fan control” isn’t a physical switch tho, it’s an electronic switch that leaks trace current thru the bulb.
