The LED's in the inside door grips are the only thing which illuminate. In the rear, the centre light comes on via the switch in the front or from opening the door. The two rear reading lights don't thought. The lighting under the wing mirrors flicker. I did take a bulb out and they look original, I didn't test the bulb however holding it up to the light the filament still seems to be intact.

The lights in the wing mirrors which illuminate when you unlock the car, are they LED out the factory? Mine flicker like crazy and I’m wondering if someone has converted to LED? If this is the case it may be causing the problems with the front interior lighting?

None were LED from factory.
