Abstract
A motor vehicle headlamp with a front glass having first prismatic surfaces which raise the horizontal cut-out line of one half of the dipped beam on the side of the road on which the vehicle is travelling so that the cut-out line consists of two horizontal lines joined by an oblique line, the lower horizontal cut-out line being on the side along which traffic travels in the opposite direction. A second prismatic surface is provided on the headlamp glass alongside the first prismatic surfaces. This second prismatic surface constitutes a window which directs a beam of light above the upper cut-out line of the dipped beam to illuminate objects on the vehicle's side of travel above the level of upper cut-out line.
