I have an older Vespa scooter. The turn signal circuit is very primative. A thermal flasher controls a lead to the handle bar switch that selects the right or left turn signal. The turn signal "beeper" is a piezo buzzer on the "flashing line" to the handle bar. I recently purchased a product by a company called Kisan, that replaces the thermal flasher with a Pulse Width Modulator (PWM) unit that allows the turn signals to be used as running lights. I guess with a half duty cycle, the left and right turn signals both appear to be continuously lit at half brightness. When the turn signal is activated, the correct turn signal flashes at full brightness.
My problem is with the piezo buzzer in the circuit, it sounds continuoulsy since the turn signal circuit always has a voltage on it. I've unplugged it, but now I don't have a turn signal beeper.
Is there a circuit design that would ignore the half duty cycle of the running lights but pass the flashed full duty cycle of the turn signals to the beeper? In this way I could have the best of both worlds -- running lights and a turn signal beeper. Thanks for your help.
