What is the small dot on the headlight cover?
1 Answers
The small dot on the headlight cover is actually a convex lens on the headlight, designed to diffuse light and ensure even distribution of illumination ahead, preventing concentrated beams that could create blind spots. Here's an introduction to car lights: 1. Headlights: Commonly known as front lights, they come in low beam and high beam variants. Their primary function is to provide illumination for night driving. Low beams are used in urban areas with streetlights, while high beams are for rural roads or highways without adequate lighting. There's also a high-low beam switch used for signaling or overtaking. Remember not to keep high beams on continuously during oncoming traffic, avoiding becoming a so-called 'high beam hog'. 2. Width indicator lights: Mainly used at night to display the vehicle's width and length, alerting other drivers and pedestrians to your presence. They should be turned on when rear visibility is poor through the mirrors or during rainy/foggy conditions to enhance driving safety. 3. Daytime running lights: To avoid increasing battery load, headlights shouldn't be used during daytime. These daytime running lights were created specifically for daytime driving to alert other road users. Typically using white LED lights, they're energy-efficient, not overly bright, yet serve as effective warning signals.
