How can dirty headlights affect driving?

Dirty headlights can greatly reduce the ability to see while driving. When headlights are obscured by dirt, grime, or other contaminants, the light emitted is diminished. This results in less illumination of the road ahead, making it more difficult to see objects, pedestrians, or road signs, especially in low-light conditions such as during nighttime or inclement weather. The reduced visibility can increase the risk of accidents, as drivers may not be able to react in time to hazards that would have been visible with clean headlights.

In addition, dirty headlights may scatter the light in an unpredictable manner, leading to further visual impairment. Proper maintenance and cleanliness of headlights are therefore essential for safe driving.
