Abstract
A flasher unit is provided with a comparator whose output signal is fed to a pulse generator for producing the flash frequency signal, the comparator being supplied with a reference voltage at one input and a voltage dependent on the current passing through the flasher lamps at the other input and with a switch element which changes the reference voltage in accordance with the comparator output signal such that the comparator produces an output signal for the whole of the light up time of the lamps.
