The sunshade may be equipped with a lighted vanity mirror. The lighted mirrors activate when the user raises the mirror door. Use the switch located next to the left lens in order to set the lamps. The vanity mirror harness extends up the windshield pillar to a connector that attaches to the lamp harness. Insert a flat-bladed screwdriver between the lens and the housing in order to remove the lamp lenses. The right and left lenses are not interchangeable.
