In a lamp you can have three settings with two filaments. One filament is for dim. When it is on, the bulb is dim. One filament is medium. When only it is on, the light is medium. When both filaments are on, the bulb is bright. In auto and motorcycle applications headlamps can have 2 filaments. A 'dip' beam and a 'High' or 'Main' beam. When the High Beam is on the Dip is off and vice versa.
