Red lights under motor arm flickering...problem ?

[Propking]

During my last flight I noticed the red lights under one of the motor arms was flickering. Has anyone had this before and if so is there an issue. Thanks.

I guess that this is a LED problem, not motor... Just replace the ESC if flickering is bothering you...

Cheers!
