Abstract
A bowl-shaped reflector for a vehicle headlight produced by a casting process has a flattened section which extends to its outer edge. Grovoes are formed on an interior side of the flattened section which are elongated substantially in the direction of an optical axis of the headlight. The breadth and depth dimensions of the grooves are related to one another, and side surfaces defining the grooves have surface shapes such that, light rays falling directly in the grooves from a dim-light filament of a bulb mounted in the reflector are reflected a plurality of times on wall surfaces defining the grooves.
