  • Patent number: 5455558
    Abstract: A turn signal alert device adapted to be easily retrofitted on an automobile which provides an audio signal when the turn signal indicator of an automobile is activated. This device includes a time delay element which delays turning on the audio signal for a predetermined time period after the turn signal indicator has been activated. A wafer-like connector couples the device across the flasher relay of the turn signal indicator, with the prongs of the flasher relay being inserted into openings in the connector with conductive elements at the openings to make electrical contact with the prongs. The device includes an audio element which is connected electrically across the flasher relay to one side of the battery power supply and the other side of the battery power supply through the filament of a light bulb in the turn signal indicator. A delay means provides a predetermined time period between a series of audio alert signals until the manually activated switch is deactivated.
