Abstract
Abstract In a direction-indicating and warning blinker system for vehicles, in particular motor vehicles, the direction-indicating lamps and the blinker unit are wed to apply the flashing or blinker signals, controlled by the direction indicator switch, separately on either the one or the other side of the vehicle, and to apply the warning blinker signals, controlled by the warning blinker system switch, simultaneously on both sides of the vehicle. The system comprises additional lamps which are controlled by the blinker unit. One end of the additional lamps are connected to the control output of the direction indicator switch. Their other terminals are connected in common to the head lamp light switch. When the latter is ''''on'''', the supply voltage is applied to the additional lamps out of phase with respect to the direction-indicating lamps.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
191 words
A combined direction-indicating and warning blinker system for vehicles having head lamps and a power source, comprising: switching arrangement connected to the power source and having a pair of output terminals each corresponding to one side of the vehicle; said arrangement having direction indicator switch means for selectively directing flow of current to the terminals and blinker means for intermittently interrupting the current flow; a first set of direction-indicating lamps coupled to one output terminal of the switching arrangement; a second set of direction-indicating lamps coupled to the other output terminal of the switching arrangement; a light switch connected to the power supply and in series with head lamps of tHe vehicle; and a first and second set of additional lights, the first set being connected between said light switch and one of the output terminals and the second being connected between the light switch and the other of said output terminals said additional lamps consuming substantially less power than either the direction-indicating lamps and the head lamps so that when an additional lamp or a head lamp and a directionindicating lamp are connected in series only the additional lamp lights.
