Sunshade Mirror Lamp

The sunshade mirror lamps turn ON when opening its mirror cover. The sunshade mirror has a switch that closes, providing ground to the lamps, when the mirror cover is open and the switch opens when the cover is closed. The switch receives ground through CKT 850.

Power to the sunshade mirror lamps is provided by the BCM through CKT 1732 in order to be protected by the inadvertent load (battery rundown) protection in case a mirror cover is left open.
