Does the illumination distance of motor vehicle lights at night change from near to far?
1 Answers
Distance changing from near to far occurs when transitioning from a curve to a straight section. The methods for judging road conditions and terrain while driving with lights at night are as follows: 1. Method one: If you notice that the illumination distance of your car's headlights changes from far to near while driving, the road ahead may be entering a curve with a mountain or barrier on one side, reaching the low point of a slope, or approaching or entering an uphill section. 2. Method two: If you notice that the illumination distance of your headlights changes from near to far while driving, the road ahead may be transitioning from a curve to a straight section, entering a downhill slope, changing from a gentle downhill to a steep downhill, or transitioning from a downhill slope to level ground. 3. Method three: If you notice that the headlight illumination leaves the road surface while driving, the road ahead may have a sharp curve, a large pothole, or be reaching the top of a slope. 4. Method four: When the illumination shifts from the center of the road to the side, the road ahead may have a regular curve or a series of curves. In the case of a series of curves, the illumination will shift from one side of the road to the other accordingly.
