Claims

[Scope of utility model registration request]

In a vehicle display device that is arranged at the rear of a vehicle body and connected to a power source via a lighting switch, and when the switch is turned on, a light source is turned on to display a warning, a message, a vehicle name, etc. to following vehicles. A display device for a vehicle, characterized in that a photosensitive element is incorporated in the electric circuit of the device, the electrical characteristics of which change when external light from the rear of the vehicle body is received, and which lights up the light source.
