I replaced my side mirrors with Clearview style copies, been working fine for a long time. The mirror lights are LEDs with resistors installed. Just recently they sometimes work and sometimes don't:

Lock/unlock car - don't work.
Hazard lights switch - don't work.
Normal indicators when driving - work fine.

Any ideas? All other indicators rear/front/bullbar work 100% all the time.

Could only be a fault with the mirrors then. I'm not sure on the wiring with them but it is a single wire from BCM to the mirror plug on the door, or bad earth when car moving but doubtful.

Pull a mirror off and plug an original in and see if the indicators work as expected. You need to work backwards and this will be the easiest way to start the diagnosis process in this case.
