A vehicular rearview mirror and light assembly which provides map and/or courtesy lighting for the vehicle interior. One or more separate housings are removably secured to the back of the mirror case and support one or more light assemblies within the space interior of the mirror case through one or more openings in back. Each assembly may include one or more light sources. A reflector/heat sink and/or a light directing lens are optionally included. Preferably, when mounted in a typical rearview mirror position adjacent a windshield, light is directed downwardly and laterally outwardly of either end of the assembly, toward the driver and front seat passenger and laterally inwardly toward the center or console area between the driver and passenger. Lighting of the instrument panel and glare in the driver's eyes are avoided or minimized.
