Abstract
A head lamp module for a motor vehicle is provided, and includes one single printed circuit board, a first group of light sources, a second group of light sources, a lens and an optical device. The first group of light sources and the second group of light sources are both arranged on the printed circuit board. The first group of light sources and the second group of light sources emit light to the optical device. The optical device is adapted to guide the emitted light in a direction towards the lens. The light leaves the head lamp module through the lens.
