Signalling circuit for brake lights which incorporates a double switch 1 composed of the contacts 2 and 3 which have a different light or separation between both and are actuated by the brake pedal. A relay 4, powered by the contacts 2, is responsible for opening the circuit powered by the contacts 3, by means of the contacts 7. A second relay 5 closes the emergency branch circuit with the contacts 8 when it is powered by the contacts 3 without allowing time for the contacts 7 to open. This circuit automatically powers the conventional brake lights 11 and 12 or powers these together with the emergency brake lights 9 and 14, conditioned only by the speed we apply to the depression of the brake pedal. It applies basically to motor vehicles and to the industry in general, providing us with a different signal according to whether we apply greater or lesser speed when actuating the double switch 1. <IMAGE>
