The method involves activating a signal arrangement (1) by pulse width modulation (PWM) signal and driving the signal arrangement by an asymmetric bus communication. The voltage at control input (13) of signal arrangement is measured within a preset time interval. The different voltages are generated at the control input of signal arrangement, within preset time interval. The signal arrangement is displaced in bus mode or PWM mode according to measured voltage. The signaling device in bus mode and PWM mode is actuated by bus communication signal and PWM signal, respectively. An independent claim is included for multi-color signal arrangement. |
