Which statement correctly describes lighting requirements during night operations?

• A. Only headlights and taillights must be in proper working order.
• B. All headlights, taillights and running/clearance lights on all vehicles and ground equipment must be in proper working order, and the driver is responsible for their operation.
• C. Rear spotlights may be left ON when on ramps if they do not blind other drivers.
• D. Lighting checks are not required during night operations.

Answer: (B)

Lighting at night must ensure visibility and being seen on the ramp. The best statement says all headlights, taillights and running/clearance lights on every vehicle and ground support equipment must be in proper working order, and the driver is responsible for their operation. This covers the essential lights that help others see you and understand your vehicle’s size, position, and movements, and it places the responsibility on the operator to verify they work before use. The other options are incomplete or unsafe: headlights and taillights alone omit running/clearance lights; leaving rear spotlights on on ramps can blind other drivers; and lighting checks are required, not optional.
