Demand Lamps
WARNING: This page is about a different car, the 2009 Ford Flex. However, it is still accessible from the selected car via links, so may be relevant.
The demand lamps are also controlled by the SJB via the battery saver relay. The demand lamps subsystem consists of the map/reading lamps, and the LH and RH vanity mirror lamps. The SJB energizes the battery saver relay to supply voltage to the demand lamps.
