Abstract: A signal assembly mountable to an exterior of a vehicle is configured with a light-generating unit operable to emit a visually perceptible signal, and with a sound-generating unit operable to generate a sound signal. The light and sound generating units are coupled to one another to form a unitary assembly.

Abstract: A vehicle horn has data representing audio horn signals recorded in a memory. The horn includes a digital counter responsive to clock signals from an oscillator to sequentially read the horn audio data from the memory, provide the data to a D/A converter and the output audio signal to a speaker for broadcast.

Abstract: A vehicle warning system is provided having a plurality of light emitting diodes mounted on a rearward facing portion of a housing, that may be attached to the side of the vehicle. A switching transistor selectively supplies current to the LED's, through a flashing circuit. The base of the transistor is driven by electrical connection to the junction of first and second phototransistors, which are mounted on the housing and directed skywardly and rearwardly, respectively. During the day the skywardly pointing phototransistor grounds the base of the transistor so that the LED's remain off. At night, the LED's are turned on responsive to the headlights of an oncoming vehicle, which will activate the rearwardly facing phototransistor.

Abstract: An automobile security device includes a lock bar extending through a lock housing. A clamping device is fixed on one end of the lock bar, and a hook is supported by the lock housing. The lock housing and hook are axially displaceable along the lock bar, such that the clamp can be attached to a floor mounted gear select lever or gearshift lever, and the lock housing and hook thereafter moved axially along the lock bar, away from the clamp, until the hook engages the floor mounted brake handle. The lock housing is locked on the lock bar, after the unit is mounted, so as to prevent the movement of the gear select lever out of the park position, and prevent movement of the brake from the engaged to the release position. The unit may also be mounted on a steering wheel, and includes a projecting rod to interfere with the rotation of the steering wheel.

Abstract: An automobile anti-theft device is provided with a first cover which fits over a steering column-mounted ignition lock, a second cover which fits over the turn signal housing on the steering column, opposite the lock, and a flexible element that extends from one end of the first cover, wraps around the steering column over the second cover, and locks in the other end of the first cover.
