If your headlights fail while driving, what should you try first?

In the event of headlight failure while driving, the first action to take is to try the headlight switch a few times. This is because the issue may not necessarily be a complete failure of the headlights or bulbs but could stem from a poor electrical connection or a faulty switch. By toggling the switch, you might restore power to the headlights, allowing them to function again without the need for immediate repairs or replacements.

Attempting to replace the bulbs immediately is not practical while driving, as it could lead to unsafe conditions. Using high beam lights exclusively is also not advisable since high beams are designed for use in situations with no oncoming traffic and can blind other drivers. Turning on fog lights might help illuminate the road ahead in some cases, but it does not serve as a primary solution for headlight failure and may not provide sufficient lighting to safely navigate. Therefore, adjusting the headlight switch is the most sensible first step to troubleshoot the problem.
