Your car must have __________ which show objects 150 feet ahead.

The requirement for a vehicle to have low beam headlights that can show objects 150 feet ahead is crucial for safe driving, especially during nighttime or low-visibility conditions. Low beam headlights are designed to provide sufficient illumination of the road directly in front of the vehicle while minimizing glare for oncoming traffic. This ensures that drivers can see clearly and detect potential hazards well in advance without blinding other drivers.

In certain situations, such as fog, heavy rain, or when following another vehicle closely, low beam headlights help maintain visibility without causing excessive glare. In contrast, parking lights are not designed for forward illumination and are primarily used to indicate a parked vehicle's presence, while high-beam headlights, though capable of illuminating much farther ahead, can cause significant glare to oncoming drivers and are not recommended for regular use when there is oncoming traffic or when following another vehicle closely. This makes low beam headlights the appropriate choice for these conditions, ensuring both visibility and safety on the road.
