What is one visual cue that your headlights may need cleaning?

Headlights that produce a dim light are a strong visual cue that they may need cleaning. Over time, headlights can accumulate dirt, grime, and oxidation, which can significantly hinder their brightness. A clear, clean headlight should emit a strong, focused beam. If the light seems weak or has lost its intensity, it’s usually an indication that the lenses are not allowing light to pass through effectively. This necessitates a cleaning to restore their function and maximize visibility during driving, especially at night or in poor weather conditions.

In contrast, headlights that appear bright at night, flicker intermittently, or emit a blue hue can be related to other issues, such as the condition of the bulbs or electrical problems, rather than just needing a simple cleaning.
