What action should you take if your headlights fail while driving at night?

Try the dimmer switch
Turn on your hazard lights
Continue driving until you reach your destination
Pull over safely

The correct answer is: Try the dimmer switch

If your headlights fail while driving at night, the appropriate action is to first try the dimmer switch. This is a logical step because sometimes, the headlights may not be completely off but could simply be on the wrong setting, for instance, from high beam to low beam or vice versa. By adjusting the dimmer switch, you could potentially restore visibility without needing to stop the vehicle. It's important to note that if the dimmer switch does not resolve the issue, other actions are also necessary. Turning on hazard lights alerts other drivers that you are experiencing a problem. Continuing to drive without headlights presents significant dangers, as it severely reduces visibility for both you and other road users, increasing the likelihood of an accident. Pulling over safely is a prudent choice when it is clear that the headlights are not operational, but trying the dimmer switch is the first recommended action to address the immediate issue.
