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

Leaving your high beams on when your headlights are not functioning properly is not advisable because high beams can create excessive glare for other drivers, especially in cloudy or rainy conditions, or when there is oncoming traffic. If your headlights are malfunctioning, it is essential to maintain visibility without compromising the safety of others on the road.

Using fog lights, if available, can be a good alternative, as they are designed to illuminate the road directly in front of the vehicle without causing glare. Staying off the road until the issue is resolved ensures your safety and the safety of other drivers, while driving with caution is a necessary practice to minimize risks while navigating with potential visibility issues.
