Abstract

A luminous signal, which can be seen in daylight to indicate side lamps illuminated in error or their failure to operate properly, is a photo-sensitive system, controlled by exterior lighting conditions, and opening the lighting circuit operates the warning lamp. There is a warning lamp and a photo-sensitive device against the windscreen. The device consists of a photo resistance controlling the current to the base of a pnp transistor, the input of which feeds the lights and the input of which feeds the warning lamp. There is also a resistance joined to the lighting circuit via a diode.
