Demand Lamps
WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The demand lamps are provided voltage from the battery saver relay (internal to the SJB ). The demand lamps subsystem consists of the map/reading lamps, cargo lamp and the LH and RH vanity mirror lamps. The SJB energizes the battery saver relay to supply voltage to the demand lamps.
