What lights to use when navigating sharp bends?

[VanBentley]

Alternate between high and low beams at least twice. For the nighttime driving light simulation test in Subject 3, three items will be randomly selected from the following for examination. These mainly include: When about to turn at an intersection, use the correct lights (use low beams). When driving on roads with low visibility, use the correct lights (turn on high beams). When about to navigate a sharp bend, use the correct lights (alternate between high and low beams at least twice). When about to go over a slope, use the correct lights (alternate between high and low beams at least twice). When about to cross a humpback bridge, use the correct lights (alternate between high and low beams at least twice). When about to cross a pedestrian crossing, use the correct lights (alternate between high and low beams at least twice). When about to pass through an intersection without traffic signals, use the correct lights (alternate between high and low beams at least twice). When about to overtake, use the correct lights (first turn on the left turn signal, then alternate between high and low beams at least twice, and finally turn on the right turn signal). When about to meet another vehicle, use the correct lights (turn on low beams).
