Abstract
Abstract The invention relates to a vehicle-mounted device for identifying and signalling the presence of danger and/or hazardous situations, as well as for passing on such a signal to other vehicles.lt comprises a first component (1) to register the presence of a change in speed or direction of a vehicle which is greater than a threshold discrimination value, whereupon an electrical circuit (5) is broken ; a second component (2), which emits a first electromagnetic wave when the device is functioning normally, and a second electromagnetic wave when the electrical circuit (5) is broken, and a third electromagnetic wave when it is so commanded by a manual switch ; and a third component (3) which on receiving and recognising the first electromagnetic wave activates a normal function signal, on receiving the second wave emits a danger signal, and on receiving the third wave emits a hazard signal.
