Which system swivels the beam into a corner?

  • A.Adaptive front lighting using steering angle
  • B.Headlamp levelling, which compensates for the attitude of the vehicle when it is laden or accelerating hard
  • C.Automatic main beam
  • D.Matrix lighting, which switches individual segments off in order to avoid dazzling other road users encountered

Answer: A

Steering angle and speed swivel the lamp so the beam follows the road. Matrix systems shape the beam by switching segments and are a genuinely different approach, which makes the last option a real technology. Tracing the requirement back to the physical constraint that produces it makes the answer follow. Most errors here come from carrying across a result from a neighbouring case where it does not hold. Checking which component actually carries the load settles most questions of this kind at once.
