Light on the switch comes on for around a second then goes off.

TOP TIP: If you don’t have a helper, park next to something reflective. A wall or garage door will do.

I did first swap out ONLY the euro panel to my original LCM and it did not activate the rear fogs. The light came on for rear fog on the instrument panel but it did not actually light up the rear taillight.
