A vehicle headlamp system can include a plurality of low beam light sources and a plurality of high beam light sources. In one or more arrangements, the light sources can be light emitting diodes. The system can include a first light driver operatively connected to selectively supply electrical energy to a first group of low beam light sources and/or a first group of high beam light sources. The system can include a second light driver operatively connected to selectively supply electrical energy to a second group of low beam light sources and/or a second group of high beam light sources. The system can further include a controller. The controller can be operatively connected to the first light driver and the second light driver to control the selective supply of electrical energy by the first light driver and the second light driver.
