Final answer:
When driving at night, it's important to use low and high headlight beams appropriately, adjusting them based on oncoming traffic to avoid blinding other drivers and to ensure optimal visibility.
Step-by-step explanation:
When driving at night, you must use low and high headlight beams properly. The headlights on your car are designed to form a directional beam of light, which is achieved by the use of mirrors. According to the information referring to figures 25.47 and 25.46, these mirrors trap most of the bulb's light and direct it forward. To use these beams correctly, you should have your low beams on when traffic is coming towards you so that you don't blind the other drivers. High beams are used when there is no oncoming traffic, providing a more extended range of visibility for the driver. Understanding the role of headlights and how their beams function at night is crucial for safe driving.
