LED light s question

[elecmen]

Never seen this problem before. There are 2 led can lights in a shower and a fan light combo. Each has its own single pole switch wired in the same switch box. There is 4 romex 14/2s in the box. One is the feed that feeds all three switches. One goes to the 2 led can light and is daisy chained to the other led light. The other 2 go to the ceiling fan,one 14/2 to the fan and the other to the light. Everything works as it should. The problem is if you turn on the fan and then shut it off the leds blink on for a second.They are not on the same switch. I checked all connections and made sure it is wired right. What could cause this? All comments welcome. Thanks

inductive Kickback from the fan is my thought. When the fan is shut off and either acts like a generator for a split-second, or capacitors discharge, providing enough juice for the light to Blink

I’ve been noticing more and more new exhaust fans now coming with a small capacitor installed near the motor, I believe to help quench the inductive kickback.
