What does it mean when the illumination distance of vehicle lights changes from near to far at night?
1 Answers
If you notice that the illumination distance of the lights changes from near to far while driving, it indicates that the vehicle is transitioning from a curved road to a straight path or from a steep downhill slope to a gentle curve. Below is a detailed explanation: 1. Explanation one: If you feel the vehicle speed automatically decreases and the engine sound becomes muffled, it means the vehicle is climbing an uphill slope or entering a difficult road section. 2. Explanation two: If you feel the vehicle speed automatically increases and the engine sound becomes lighter, it means the vehicle is descending a downhill slope. 3. Explanation three: If you notice that the illumination distance of the vehicle lights changes from far to near while driving, it indicates that the vehicle is approaching an uphill slope, a sharp curve, or the low point of a rolling road section.
