This Is A Great Idea As A Deterrent To Car Thieves. You Simply Disconnect Your Negative Terminal, And Replace It With This On/off Switch. When You Leave Your Vehicle, Open The Hood And Switch It "off". Your Car Cannot Be Started Until It Is Switched Back On. A "would Be" Thief Will Think You Have A Dead Battery, And Move On To Another Vehicle.

* Measures about 3 inches long, and weighs about 2 ounces

* Even a car thief cannot "hot wire" your vehicle while the switch is off
