Which of the following lights should be checked during the interior light check?

The correct choice emphasizes checking the headlights and tail lights during the interior light check. This step is critical for ensuring that all essential lighting systems are operational and functioning correctly before a vehicle is put on the road.

By verifying the headlights, drivers can ensure that they have adequate visibility for nighttime driving and poor weather conditions. Similarly, checking the tail lights is equally important as these lights communicate the vehicle's presence and intentions to others on the road, such as braking or changes in direction. This helps to enhance safety for everyone, including the driver, passengers, and other road users.

In contrast, while the other options—8 Way Ambers, left turn signal, and 4 Way Hazards—are important for overall vehicle safety and functionality, they are typically part of a different light check process that focuses on exterior signaling and visibility to other drivers rather than the interior checks specifically. The interior light check mainly aims to ensure that key vehicle lights required for operation are in good working order before beginning a trip.
