MASKED HEADLIGHTS REDUCE GLARE, IMPROVE LOW-BEAM ILLUMINATION

A Swiss concept for anti-glare headlights keeps the low beam below the eye-level of oncoming drivers, yet gives extended illumination along the road surface. Devised by the creator of war-time black-out lights, the system has the dipped headlight unit set 16 in. behind a masking slot in the front of the vehicle. This is a powerful 100-watt quartz-iodine bulb in a squared parabolic reflector with no diffusing lens. Critical location of the reflector gives three focal points as the intense flat beam shines thorugh the plain rectangular opening for exceptical low- level penetration with little scatter. The lights are also said to be highly effective in fog. They are paired with conventional high-beam units for long-range lighting. Clear plastic prisms alongside each forward slot serve as side-view tell-tales when the concealed lights alone are on. The system was developed by Erical S.A., Place de la Fusterie 7, 1211 Geneva 3, Switzerland. It is seen primarily as an origianl equipment item, since on most vehicles the engine compartment layout would have to be designed to accomodate the lamp unit. /Article/
