Abstract: A control device for signal lamps of a vehicle, having a signalling circuit for generating an intermittent signal current as load current for the signal lamps, and a signal switch for activating the signalling circuit. The control device, which can be implemented easily, generates a running light function for signal lamps of a vehicle. A clock circuit is provided which drives the load current of at least two signal lamps individually in each case with the aid of a prescribed clock sequence, in which case, acting as operating voltage source for this clock circuit, the signalling circuit feeds the latter the intermittent signal current. The control device can be used both in the context of a turn flasher and hazard warning function and for signalling the state of central locking or antitheft warning systems, and merely for controlling electroluminescence luminous strips with the aim of enhancing the overall visual impression of a vehicle.
