Ljusreglage

Ljusreglage is a Swedish term that translates to light controls or lighting adjustment. It refers to the set of devices, switches, and mechanisms used to regulate lighting in different contexts, including everyday domestic lighting, automotive headlights, and professional lighting systems. The term encompasses both the act of adjusting brightness and the hardware used to do so.

In cars, ljusreglage most commonly denotes the headlight adjustment features. This includes controls for turning headlights, parking lights, and sometimes fog lamps, as well as mechanisms for adjusting the aim of the headlamps. Many modern vehicles have a dedicated headlight leveling control that moves the beam vertically to compensate for load or tilt; some systems are automatic, using sensors to maintain proper alignment. Proper adjustment is important for road safety and is checked in vehicle inspections in many jurisdictions.

Outside the automotive context, ljusreglage can also refer to dimming controls for household lighting, stage and studio lighting rigs, and other systems that regulate light output and distribution. In these settings, regulation may involve intensity, direction, duration, and sometimes color temperature.

The term is formed from ljus (light) and reglage (control or adjustment), reflecting Swedish usage of reglage to name adjustment mechanisms across disciplines.
