ABSTRACT:
A vehicular back-up lamp alarm device, comprising a sonic element, such as a buzzer, which is an integral part of the lamp base or of socket for receiving it. The sonic element is connected so it will be in parallel with the back-up lamp. Alternatively, the sonic element may be an integral part of a socket converter having a conventional lamp base and socket, and connected in parallel with the electrical connections between such base and socket. As a result, the operating voltage which is applied to the back-up lamp when the vehicle is put into reverse gear will also cause the sonic element to emit an audible alarm.
