摘要

A light-wave conductor (1) links to a light-wave generator (2) and fits behind the outer wall (3) of a bumper bar and an absorber element (4), running essentially across a vehicle in front of a bodywork cross-member (5) or an intermediate part (6) fastened and supported on it. Forming a reverse loop on the outer side, it runs towards a light-receiving device (9).
