Abstract: An audio indicator is provided for a motor vehicle direction signal circuit of the type including a battery and a turn signal switch connecting the battery to at least one indicator lamp through a set of switchable contacts in a plug-in timer can, and with structure for intermittently opening and closing the contacts to flash the indicator lamps. The audio indicator has an electrically operated sound generating device with a substantially greater series resistance than the indicator lamps, and that is connected in parallel with the contacts of the timer can. When the timer can contacts are closed, the indicator lamps are "on", and current is shorted through the contacts such that the sound generating device is "off". When the timer can contacts are open, the indicator lamps are "off", and substantially all of the voltage from the battery appears across the sound generating device and the sound generating device is "on".
