What must be done to auxiliary lights that are inoperative?

When auxiliary lights are inoperative, they must be repaired at the next forward repair point. This is important because auxiliary lights are essential for ensuring visibility and safety, especially in low-light conditions. Maintaining the functionality of all lighting systems is crucial for safe operation, as they help signal intentions to other vehicles and improve visibility for various operational scenarios.

Repairing inoperative lights promptly mitigates potential risks and ensures compliance with safety standards and regulations. While it may be tempting to prioritize headlight operation over auxiliaries, doing so can lead to unsafe conditions, especially in areas where enhanced visibility is needed. Ignoring the issue, as suggested by some of the other options, could compromise safety and operational integrity, making timely repairs essential.
