The invention belongs to the technical field of automobiles, and relates to a vehicle light-emitting sign which comprises a circuit board, a light uniformizing plate and a sign board, a vehicle sign pattern is formed on the sign board through cooperation of a shading area and a light-transmitting area, a light-emitting source is arranged on the circuit board, and incident light of the light-emitting source points to the light uniformizing plate. Incident light of the light emitting source can enter the light uniformizing plate in the thickness direction of the light uniformizing plate, a light reflecting cone is arranged on the surface, opposite to the light emitting source, of the light uniformizing plate, and the light reflecting cone and the light emitting source are arranged correspondingly. The surface of the light reflecting cone is subjected to surface treatment so as to reflect incident light of the light emitting source to the peripheral area of the light reflecting cone in the plate surface direction of the light homogenizing plate, and light scattering concave points are arranged on the surface, facing the light emitting source, of the light homogenizing plate. The problem of convenient manufacturing is solved.
