Indicator Light On The Light Switch: Notes

WARNING: This page does not describe the selected car, but rather 46 other vehicles, including the 2008 BMW M5, 2008 BMW 650i, 2007 BMW Z4, 2007 BMW M6, and 2007 BMW M5. However, it is still accessible from the selected car via links, so may be relevant.

The indicator light (green LED) next to the "A" (= "automatic driving lights control" and "adaptive headlights") has two display functions:

The indicator light lights up permanently when the automatic driving lights control or adaptive headlights function is switched on (= light switch in position "A").
The indicator light flashes if a fault develops in the adaptive headlight system.
The indicator light thus supports diagnosis of the adaptive headlights.

The indicator light is actuated by the control unit for adaptive headlights.
