The invention relates to a multi-functional vehicle lamp and belongs to the technical field of vehicle lamps. According to the multi-functional vehicle lamp, one or more ultrasonic wave radar sensors and/or one or more video cameras are installed on a lampshade of the vehicle lamp, so that the vehicle lamp has a radar ranging function and a video image function besides a lighting function. The multi-functional vehicle lamp not only can be a high beam lamp, a low beam lamp, a daytime running lamp, a fog lamp, a turn signal lamp, a fender side turn signal lamp, a rearview mirror side turn signal lamp, a width lamp, a stop lamp, a backup lamp and a reflector, but also can be an arbitrary combining piece of the above components such as a combining headlamp and a combining tail-lamp. According to the multi-functional vehicle lamp, the ultrasonic wave radar sensors and the video cameras are integrated on the vehicle lamp, circuits are the same with that of the vehicle lamp, installing and maintaining are convenient, and other portions of a vehicle is not affected; and the ultrasonic wave radar sensors and the video cameras can be arranged densely, so that obstacle detection and image observation in a large angle range and with no dead zones are formed.
