The invention discloses a light-emitting automobile sign convenient for millimeter-wave radar penetration, which comprises a sign body and a sign base, and is characterized in that the back surface ofthe sign body is connected with the sign base in a sticking or vibration friction welding manner; a UV high-hardness finish paint layer is sprayed on the front surface of the sign body, and a silk-screen printing ink layer, a UV primer layer and a nano inorganic silicon coating are sequentially arranged on the back surface of the sign body; a light-emitting device is further arranged between thesign body and the sign base and comprises a light guide plate and an LED rubber frame, the back face of the light guide plate is installed on the sign base through screws, and the front face of the light guide plate is connected with the LED rubber frame through a buckle. LED lamp beads are arranged on the LED rubber frame, and an LED lamp driving circuit is installed on the sign base and electrically connected with the LED lamp beads through wires. According to the invention, the sign body is irradiated by means of the LED lamp beads installed inside the sign, the lighting effect is good, therequirements of the 77GH millimeter-wave radar for permeability and accuracy are met, and the sign has the metal surface effect.
