What should you do to ensure the visibility of your headlights?

1. Only use them at night

2. Clean them regularly

3. Replace them every year

4. Cover them during the day

The correct answer is: Clean them regularly

Cleaning headlights regularly is crucial to ensuring their visibility. Over time, headlight lenses can become hazy or dirty due to exposure to the elements, including dirt, debris, and UV rays. This buildup can significantly reduce the amount of light emitted by the headlights, impairing nighttime visibility and making it harder for other drivers to see your vehicle. By maintaining clean headlights, you enhance road safety for yourself and others, as clear headlights provide maximum illumination when driving at night or in poor weather conditions. Options that suggest only using headlights at night, replacing them annually, or covering them during the day do not effectively address the maintenance of headlight clarity and brightness. While replacing old bulbs is important, the frequency can depend on usage and the manufacturer's recommendations, rather than a blanket annual requirement. Covering headlights would actually inhibit their function and is not advisable. Thus, keeping them clean is the most practical and immediate way to ensure they remain effective and visible.
