A method of supplying current and/or voltage to a vehicle trailer as the supply of an electronic and/or electric components of a braking system of the vehicle trailer from a tractor vehicle comprising: connecting a first supply line from the tractor to the trailer's electronic and/or electric components of the braking system; and automatically connecting a brake light supply line as the current and/or voltage supply line for supplying the electronic and/or electric components of the braking system of the vehicle trailer when the supply from the connected first supply line has failed. 2. A device according to claim 1, wherein the means includes a switching device which switches the current and/or voltage supply from the second supply line to the supply line of the braking system. 3. A device for supplying current and/or voltage to a vehicle trailer as the supply of brake components of a braking system of the vehicle trailer, comprising: a first supply line connecting the braking system of the vehicle trailer with a tractor vehicle; at least one second supply line connecting the vehicle trailer with the tractor vehicle; and means for automatically connecting the at least one second supply line with the braking system of vehicle trailer in the event of a failure of the connected first supply line. 4. A device according to claim 3, wherein the second supply line is a brake light supply line. 5. A device according to claim 3, wherein the second supply line is a supply line of a right or left tail light of the trailer. 6. A device according to claim 1, wherein the second supply line is a supply line which is arranged on the vehicle and/or vehicle trailer by free plug-type connections in a socket and plug arrangement. 7. A device according to claim 3, wherein the means includes a detection device which detects the failure of the first supply line. 8. A device according to claim 3, wherein the braking system includes at least two or more of electronic control unit, pressure gauge sensors, back-up valve, anti-lock system valves. 9. A method of supplying current and/or voltage to a vehicle trailer as a supply of an electronic and/or electric components of a braking system of the vehicle trailer from a tractor vehicle, wherein a first supply line connects the tractor to the trailer's electronic and/or electric components of the braking system and a second supply line connects the tractor to the trailer, the method comprising: automatically using the second supply line as the current and/or voltage supply line for supplying the electronic and/or electric components of the braking system of the vehicle trailer when the supply from the connected first supply line has failed.
