Abstract
The present invention relates to a headlight comprising a glass lens element and a support element, such as a reflector, of thermoplastic material, such elements being associated at their periphery by matching assembly shapes of interlocking type which are fixed by an assembly glue. The headlight is characterized in that the lens is provided with three fixed internal supports cast in one piece with the lens which define a bearing plane. The lens is also provided with a further internal support having a positive offset with respect to the bearing plane. This offset is compensated by an interposed support member whose thickness is determined by the actual features of the lens.
