Question 4129
For proper use of the lights, what must you check?

- Only the adjustment, but fairly regularly.
- The adjustment, operation, and condition of the system.
Show answer and explanation
Correct answer: The adjustment, operation, and condition of the system.
Check three things: that all the lights turn on, that the bulbs and lenses are in good condition, and that the headlights are properly aimed so they light the way without blinding others. Checking only the aim is not enough. You do not need to go to a repair shop to check that they work; just turn them on facing a garage wall. In the image, a mechanic checks the headlight aim with a device placed in front of the car.
