Abstract: A motor vehicle light is comprised of a high intensity lamp for attaching to a motor vehicle, such as to a side mounted rear view mirror. The lamp includes optics for focusing a light beam into a small spot on the road in front of the vehicle. The lamp includes a hinge for being pivoted to direct the light spot for marking the track of the vehicle to help the driver position the vehicle within the lane. In a second embodiment, the lamp is linked to the steering apparatus of the vehicle for simultaneous movement so as to mark the track of a rear wheel during a turn.

Abstract: The present breathing valve is comprised of a hollow tubular housing sized to fit snugly inside a nostril. The housing is provided with an external thread for screwing into the nostril. A turning tool is provided for screwing and unscrewing the housing by engaging the interior of the housing. An air flow restricting device is provided within the housing. In one embodiment, the restricting device is comprised of a constricted passage for reducing air flow and increasing air pressure within the respiratory system of the user. Oxygen absorption is improved enough by the increased air pressure to eliminate the need for supplemental oxygen for people at high altitudes, and for people with respiratory problems. In a second embodiment, the restricting device is comprised of a movable restricting device which is moved to an open position during inhale to allow free passage of air.
