  • Self-contained turn signal indicator unit
    Patent number: 7554436
    Abstract: A self-contained turn signal indicator unit for signaling to the hearing impaired driver of a motor vehicle that the vehicle's turn signals are activated. The indicator unit is attached to the cover of the vehicle's steering column and produces a loud audible signal and a light signal when the turn signal lever is moved to the turning position. The circuitry includes a battery, a turn switch activated by movement of the turn signal lever, and a buzzer and a lamp. A volume control, operable by a user, controls the volume of the sound. An optional timed switch for turning off the circuit has a normally closed position and has an open position for a predetermined period of time after the turn switch is closed and remains closed.
