A second information display may be included in the assembly to display other information related to the vehicle or vehicle accessories such as one or more of vehicle related status or warning information comprising supplemental inflatable restraint system information, vehicle accessory information, communication information, status of tire inflation information, weather information, traffic information, toll booth information, or the like. The interior rearview mirror assembly may also include at least one additional electrical accessory such as an interior light, a phone accessory, a microphone or the like.
