Which of these is NOT something you should do if your headlights are not working properly?

If your headlights are not functioning properly, leaving your high beams on is not a suitable solution. High beams are designed for use in dark environments to provide better visibility, but they can blind other drivers when used improperly, especially in urban settings or when other vehicles are nearby. If your headlights need attention, engaging high beams may create a hazard rather than resolving the issue.

Cleaning your headlights can enhance brightness and visibility if they are dirty or foggy. Adjusting your headlights ensures they are properly aimed to illuminate the road effectively without blinding oncoming traffic. Replacing bulbs is essential when they are burned out. Thus, while there are appropriate actions to address headlight issues, using high beams as a fix is not advisable and does not rectify the underlying problem.
