A headlight is a powerful light mounted on the front of a vehicle, typically a car, truck, or motorcycle, used to illuminate the road ahead and enhance visibility during night driving or in low-light conditions. It helps drivers see obstacles, road signs, and other vehicles more clearly, ensuring safety. Headlights often have different settings, such as low beam for regular driving and high beam for situations requiring maximum light, like on dark roads. Modern headlights may also feature LED or HID technology, providing brighter, more energy-efficient illumination. The design of headlights can vary, including round, rectangular, or angular shapes, and may be paired with additional features like fog lights or adaptive lighting systems.
