Abstract: The system is designed to instantaneously produce the activation of the emergency lamps included in the vehicle wherein the system is applied in the event of collision, sudden braking, overturning, etc. The system may be provided fully independently from the vehicle's standard emergency lights or else may form a complement thereof to be activated as a result of any of the abovementioned situations. The activation of the system is based on the movement of a piston in the event of collision, sudden stoppage or similar situations, closing a circuit that feeds the emergency lamps via remote-controlled switches associated to lamps on either side and via an interlocking remote-controlled switch which is deactivated through a master switch that is a part of the circuit itself.
