High and low beam with a single lamp, double charge tube

    Analogous to the double filaments present in an H4-lamp, one for dim and one for main light, it is proposed to use two automotive head lamp discharge bulbs in line. Switching from dim to main light or vice versa is relatively simple then, as physical displacement of the single automotive head lamp burner and mechanical parts to realize said displacement are avoided.
