Abstract

A portable bar attaches tangentially and locks to a vehicle steering wheel, preferably at the uppermost section of the rim, and extends to where it is fully visible from outside of the vehicle. The bar is a holllow tube in which a pair of clamping members, one being a fixed section of the tube and the other part hinged thereto, surrounds and is locked about the steering wheel rim. A cavity in the tube protectively encloses, along with anti-saw-through bars, alarm circuitry and the batteries therefor. Light and sound annunciators on the bar and a flashing LED armed-condition indicator are provided. A panic button on the outside of the tube to manually trigger the alarm, and push button selectors enclosed in the tube and accessible only when the device is unlocked to arm and disarm the alarm and to activate the light to serve as a flashlight or emergency flasher.
