ABSTRACT:
The invention relates to signalling, particularly road signalling, means. A considerable variety of illuminated and reflective signalling means are known to give advice to the driver of a particular vehicle and of great value to the driver of a vehicle during the hours of darkness on unlit roads or in inclement weather where mist and fog shroud a road. Such known signalling means cannot satisfy the important need to give advice to a driver of a vehicle of the presence of another vehicle closely ahead, and which is of particular importance in misty or foggy conditions. The primary objective of the invention is to provide a signalling means that can satisfy this requirement, which objective is met by a construction comprising at least one means (7, C3) able to be charged by light from a vehicle headlight, and a visible signal means (8; 13, 15) connected to and activated by said chargeable means (7, C3), and whereby on being charged, said chargeable means (7, C3) activates said signal means (8; 13, 15) for a discrete period of time after said headlight has ceased to illuminate said chargeable means (7, C3) and until said chargeable means (7, C3) has discharged. As a result, a trail of signals is permanently provided behind a lead vehicle to give warning to a vehicle behind of its presence and to a distance that constitutes a safe braking distance.
