Which system adjusts headlamp aim for vehicle load?

  • A.Automatic main beam
  • B.A manual adjustment at the lamp, which is set during the annual inspection and requires no further attention
  • C.A headlamp levelling system
  • D.The adaptive front lighting system, which swivels the beam into corners according to the steering angle applied

Answer: C

Levelling compensates for the nose up attitude of a laden vehicle, either by a dashboard control or automatically from suspension sensors. Adaptive lighting swivels the beam, which makes the second option a real system with a different purpose. The order in which the effects act is what decides the outcome, so it is worth establishing first. Naming the cost of a choice alongside its benefit is what turns a fact into a design decision.
