At what settings should headlights function during PDI?

During Pre-Delivery Inspection (PDI), it is essential to ensure that the headlights function properly in both dim and bright settings. Verifying these settings confirms that the vehicle's lighting system operates effectively under various conditions. The dim setting, or low beam, is typically used for nighttime driving or in inclement weather, providing adequate illumination without blinding oncoming drivers. The bright setting, or high beam, is utilized in dark areas where more visibility is needed. Ensuring both settings work correctly not only enhances safety but also complies with legal requirements for vehicle operation.

The other options focus on either the headlights being completely off or on, the functionality of high and low beams without considering the dim and bright distinction, or they include unrelated features of the vehicle's lighting system, such as indicators and emergency lights, which are not part of the headlight functionality test during PDI.
