What is the headlight?
1 Answers
Headlights generally refer to high beams and low beams, while small lights refer to contour lights, also known as width indicator lights. Here are the relevant details: 1. Function of small lights: Small lights are mainly used during dusk, dawn, or daytime when visibility is low but no illumination is needed. Their primary purpose is to signal the position of your vehicle to other drivers, not to provide illumination; they serve as warning signal lights. 2. Function of headlights: Headlights, on the other hand, are primarily used for illumination during nighttime or in weather conditions like heavy fog or rain that require lighting. They include both high beams and low beams. 3. Difference between high and low beams: Both high and low beams are used for illumination but have distinct differences. High beams are angled higher, providing illumination over a longer distance, while low beams are angled lower with a shorter illumination range. Normally, low beams are used, but when driving above 30 km/h, high beams can be employed. Additionally, high beams offer a longer field of vision, allowing drivers to assess road conditions ahead. They can also expand the driver's visual range in foggy or rainy conditions and serve as a safety measure by alerting oncoming vehicles in poor lighting conditions. When passing through intersections at night, quickly switching between low and high beams can alert other vehicles at the intersection. Modern car headlights include low beams, high beams, width indicator lights, and turn signals, with some vehicles also equipped with fog lights.
