Final answer:
To observe the headlights on your car, avoid looking directly at them and instead look slightly to the side or downwards while still being able to see them out of the corner of your eye. This allows you to check if the headlights are properly functioning and if they are aimed correctly.
Step-by-step explanation:
When observing the headlights on your car, it is important to follow certain precautions to protect your eyes. One way to observe the headlights without looking directly at them is to look slightly to the side or downwards while still being able to see them out of the corner of your eye. By doing this, you can notice if the headlights are properly functioning, if they are aimed correctly, and if they are sufficiently bright. It is also important to observe if both headlights are working, as having only one functioning headlight can impair visibility and pose a safety risk.
