Title: Headlamp lighting for car - has optical sensor behind headlamp lens or supplied by optic fibre from lens to establish traffic situation
Inventor: HEIZMANN FRIEDER ING
IPC: G01S17/931
Filed: 1992-05-14
Abstract: The headlamp lighting is provided with conventional bulbs and reflectors with lenses to vary the transmitted light distribution.
