And also some cars have a bi-xenon assembly. There is only one pair of lamps but the low/high beam switching is achieved by means of motors/solenoids which move a metal plate. In low beam, the plate covers part of the reflector or bulb. When in high beam the solenoid retracts the metal 'curtain' and exposes more reflector or bulb.
There are also setups where a solenoid moves the bulb itself back and forth, changing the focal charactersitics of the lamp.
But the most common setup are separate highs and lows. Simple and foolproof.
