Vanity Lamp: Description and Operation
The inadvertent power relay provides battery positive voltage to each vanity mirror lamp. When the vanity mirror cover on the sunshade is opened, its
switch closes to provide a ground circuit and the vanity lamp illuminates. The vanity lamps are grounded at G203.
