Demand Lamps
WARNING: This page is about a different car, the 2011 Lincoln MKT. However, it is still accessible from the selected car via links, so may be relevant.
The demand lamps are controlled by the SJB via the battery saver relay. The demand lamps subsystem consists of the map/reading lamps and the vanity mirror lamps located in the visors. The SJB energizes the battery saver relay to supply voltage to the demand lamps.
