Which step is important to take when checking lights?

Ensuring that headlights, signals, and taillights are functioning is essential for several reasons. First, these lights are crucial for safe driving; they help you see the road ahead during low visibility conditions and make other drivers aware of your presence on the road. Regularly checking all lights ensures that they are operational and helps prevent accidents caused by non-functioning lights. Additionally, this practice is important for compliance with traffic laws, as operating a vehicle with broken lights can lead to citations. Checking only high beams, using a phone, or turning on hazard lights does not comprehensively assess the vehicle's lighting system, which is why focusing on all essential lights, including headlights, turn signals, and taillights, is the most important step.
