  • Waterproof valve stem safety light for vehicles
    Patent number: 6070997
    Abstract: A symmetrical safety light for wheeled vehicles is turned on by relative rotation of a removable plug in a housing that pushes a battery in the housing against the resistance of a spring. The light is turned off by relative rotation of the components in the opposite direction, which allows the spring to push the battery out of contact with a conductor from the light.
