Abstract

The invention relates to a motor vehicle headlight () having a lamp unit (), which has at least one light source () and an optical attachment () having a light emission surface (), and having a projection lens () downstream of the lamp unit, wherein the optical attachment has a plurality of waveguide elements (), each having a light coupling surface () for feeding in light from the at least one light source and having light decoupling surfaces () arranged in the light emission surface of the optical attachment and projects a light pattern forward in the traffic space, the waveguide elements extend between the light coupling surface and the light decoupling surface, wherein the light decoupling surface has a greater area than the light coupling surface, and each waveguide element is laterally delimited by two lateral surfaces (), from above by a roof surface () and below by a floor surface () and tapers between the light decoupling surface and the light coupling surface, wherein the width of the floor surface decreases proceeding from the light emission surface, wherein the floor surface () and/or the roof surface () of at least one waveguide element () has exactly one constriction () in respect of the width thereof between the light decoupling surface () and the light coupling surface (), which has the smallest width (b) of the floor surface and/or of the roof surface.
