Abstract (en)
[origin: WO8911984A1] A temporary lighting system (10) for vehicles in tow comprises a pair of radio frequency controlled lighting assemblies (16, 18) that each include a rechargeable battery (46) as well as magnets (50) for coupling of the assembly to, for example, the trunk of a disabled vehicle (22). A transmitter (12) is mounted within a cab of the towing vehicle (14) and is electrically connected to the brake and turn signal circuitry of the towing vehicle (14) in order to transmit a coded wireless signal to each of the lighting assemblies (16, 18). A receiver (40) in each lighting assembly decodes the signal and illuminates a bulb (32) within the assembly in order to signal drivers behind the disabled vehicle (22) that the operator of the towing vehicle (14) is about to effect a turn or has applied the brakes. The bulb (32) of each lighting assembly also includes a filament which can be automatically or manually energized to serve as running lights.
