I contacted the vendor I bought my lights from and they sent me capacitors for free! Installed, no more flickering / error messages

Guys, i need some help, have replaced stock rear lights with LED ones and are all working fine apart from a slight flicker on the side lights. I have some capacitors, but unsure where to attach them (what wires). The offending light has a black wire (currently snipped - dont ask) and a green/white wire (see attached).

Where do i attach the capacitor to? Thanks in advance and afterwards.

I have noticed that the offending light only flickers when on full beam, if the side lights are just on, its fine and doesnt flickers, but once you switch full beam on, it flickers and its only the drivers (Right hand drive) side that does this. Its the light with the purpule arrow (stock photo). Any ideas?

In theory you need tap the positive lead of the capacitor into the green wire and the negative lead of the capacitor into the black wire but it is odd that one one LED flickers and only when high beam is on. It sort of infers that the LED tails may already include some form of capacitor in them and one of yours is faulty.

Are the LED tails intended for facelift cars (2004-2006) or are they for the earlier model?

Just want to thank everyone for their contributions to this thread.

I bought some LED tails, turned off the cold/hot monitoring via BMW Scanner 1.4.0 and soldered a 4700uf 25v capacitor to the green and black lines going to the brake lights.

They work perfectly!

The car is a 2005 and I bought non LCI tails.
