Final answer:
For vehicle safety, all lights must be checked often and any burned out bulbs replaced promptly. Do not look directly at very bright lights to avoid eye damage.
Step-by-step explanation:
The correct statement about checking your lights is: You must check all your lights often, and promptly replace any burned out bulbs. It's essential for safety that the headlights on your car and all other lights, including brake lights, turn signals, and reverse lights, are fully functional.
While checking your lights, you should look for any dimming, flickering, or lights that have burned out. It is important not to look directly at very bright lights, such as headlights, to avoid damaging your eyes. Ensure that you rectify any issues promptly, as functioning lights are critical for visibility and communication with other road users.
