An interior rearview mirror
assembly for vehicles incorporates a reflective mirror element for viewing by a user of the mirror
assembly, a lip formed from moldable polymeric resin selected to expand sufficiently when heated to allow snap in
insertion of the reflective mirror element while the lip is warm and flexable, a carrier located to the rear of the reflective element such that the carrier is closer to a
windshield of the vehicle than the mirror element when the mirror element is mounted in the vehicle, at least one electrical accessory, and an
electrical connector adapted to receive a connector from the vehicle electrical
system with the electrical accessory connected to the
electrical connector. Preferably, the electrical accessory is supported by the carrier and is selected from a variety of
electrical devices, lamps, lights, sensors and the like.
