ABSTRACT:
Apparatus for lighting and/or indicating purposes, on a vehicle such as a motor vehicle that has a rear fog lamp. The apparatus includes an electrical supply and a control circuit connecting the electrical supply to the fog lamp and/or an indicator. The control circuit is responsive to activating signals from a fog detector that is adapted to produce the activating signal when a condition of reduced visibility exists in the environment of the vehicle. This activating signal, moreover, is generated in response to electromagnetic waves reflected to a receiver coupled to the fog detector.
