Audible pedestrian turn signal alert system |
摘要 |
A audible pedestrian alert system for use with vehicles having a wide turning radius such as buses and trucks. A device is disposed in the rear wheel well of the vehicle and is operatively connected to a conventional vehicle turn signal circuit including a battery and a turn signal switch operable to selectively connect the battery through a switching device to at least a first turn signal indicator lamp through a first contact point and to at least a second turn signal indicator lamp through a second contact point. The device includes a sound generating device and a timing and signal conditioning circuit operably connected to the turn signal switch for connecting the battery to the sound generating device. Upon activation of the turn signal switch, a pulsed tone is audible for a pre-determined time.
