How often should you clean your headlights?

1. Every month

2. Only when they appear dirty

3. As often as you clean your windshield

4. Once a year

The correct answer is: As often as you clean your windshield

Regularly cleaning your headlights is essential for maintaining their clarity and ensuring optimal visibility while driving. Headlights can become foggy, dirty, or even discolored over time due to a combination of road grime, salt, and weather conditions. Cleaning your headlights as frequently as you clean your windshield ensures that they remain free from obstructions that can reduce brightness and effectiveness. Since windshields collect dirt and grime as well, a similar approach to headlight maintenance promotes safety and visibility. Keeping both areas clean can prevent accidents, especially during nighttime or inclement weather. Other choices suggest less frequent cleanings, which may allow dirt buildup affecting the headlights' performance. Cleaning based on appearance might lead to neglecting them until they become significantly impaired, while an annual schedule may not be adequate given the varying conditions vehicles face throughout the year. Therefore, integrating headlight cleaning with the routine of windshield maintenance ensures both are kept in optimal condition for clear visibility on the road.
