What are you required to check when one of the vehicle’s lamps is not working?
- Correct answer: The bulb and the fuse connected to it.
- The intactness of the lamp’s lens.
- The functionality of the lights handle.
- The battery’s voltage.
Why this is the answer
The correct answer in the official bank: The bulb and the fuse connected to it.
When only one lamp fails while the others work, the battery and the lights switch are probably fine, since they also serve the other lamps. The usual cause is a burnt-out bulb or a blown fuse in that lamp's circuit, so those are checked first. A cracked lens does not stop the bulb from lighting.
