Lights

CABIN_LIGHTS_SWITCH

What it is

Cabin lights switch

The position of the physical switch which controls the cabin lights. This might be different than the CABIN_LIGHTS_STATE if the lights are on because a door is open or because of a voice command. For example, while the switch is in the "off" or "automatic" position.

This property is defined as VehiclePropertyAccess.READ_WRITE, but OEMs have the option to implement it as VehiclePropertyAccess.READ only.

How the ID is built

A property ID is a 32-bit value packing four fields. Reading 0x11400f02 apart:

Field	Mask	Value	Means
Group	0xf0000000	0x10000000	SYSTEM
Area	0x0f000000	0x01000000	GLOBAL
Type	0x00ff0000	0x00400000	INT32
Ordinal	0x0000ffff	0x00000f02	0xf02

Reading it from an app

CarPropertyManager mgr = (CarPropertyManager)
        car.getCarManager(Car.PROPERTY_SERVICE);

int value =
        mgr.getIntProperty(VehiclePropertyIds.CABIN_LIGHTS_SWITCH, 0);

This property can be read and written, though an OEM may implement it as read-only. It fires a callback whenever the value changes.
