A power supply method of supplying power to a dual-mode automobile headlight light source able to provide either lighting in main beam mode or lighting in dipped beam mode, wherein the light source is supplied with electrical power at a first voltage when it is in main beam mode and at a second voltage when it is in dipped beam mode, the second voltage being lower than the first voltage.
A headlight for automobile vehicles, comprising:
- a light source associated with a lighting module generating a light beam,
- a removable cap, and
- power supply means for supplying a voltage to the light source,
- wherein the power supply means are adapted to generate alternately a first voltage when the headlight is in a main beam mode and a second voltage, lower than the first voltage, when the headlight is in a dipped beam mode.
