This headlamp unit fits Citroën 11CV and 15CV models. The round housing with rim allows secure mounting in the front panel. Lens and reflector work together to form a light beam that illuminates the road ahead of the vehicle. The diameter is about 210 millimetres, fitting the standard opening. The connector supports common wiring and bulb types used on vehicles from this period. The construction allows sufficient airflow around the bulb. The unit replaces an existing headlamp without changes to the bodywork. It is designed for use as a primary front headlamp and integrates into the original lighting system.
