This headlamp unit is suitable for Citroën 11CV and forms a complete housing with reflector and lens. The unit provides directed illumination at the front of the vehicle and supports safe driving in traffic. The round design with a diameter of 189 mm fits the original mounting locations of the vehicle. The headlamp unit replaces a worn or damaged component and works with the standard electrical connection. The product is aligned with the light beam pattern and mounting points of the original model, so installation can take place in the existing bodywork without structural modification.
