Do you have the adaptive lights that can "see" round corners? Have you checked the back of the lamps that no connections have worked loose? 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it

Adaptive lights do not do this.
If there's no loose connections, I would suggest a quick trip to the dealers. Malaysia Boleh!

All RRS supercharged are with adaptive lights or it optional
just a Q 2007 Range Rover Sport Supercharged, Buckingham Blue, Ivory converted to HST Silver

SOLD-V8 Defender 90

BMW's are horendous for problems like this
Sometimes its the body control ECU or even the light control module
It is all on the can lines so as Tim says it is check the connections on the back of the light, and if you have no joy off to the dealers.

Good luck with it. You don't stop playing because you get old, You get old because you stop playing.
