What percentage of LED bulbs must be functional for the vehicle to pass inspection?

The requirement for LED bulbs to be functional for a vehicle to pass inspection is based on ensuring that sufficient lighting is available for safe operation. For a vehicle to meet the inspection criteria, it is mandated that a minimum of 50% of the LED bulbs must be operational.

This percentage is established to ensure that there is adequate illumination and visibility on the road, promoting safety for both the vehicle occupants and other road users. When at least half of the LED bulbs are functioning, it signifies that the vehicle's lighting system is still capable of performing its essential duties, such as signaling, illuminating the road, and ensuring visibility during adverse conditions.

Therefore, the correct answer aligns with the safety standards set forth in the inspection guidelines, emphasizing the importance of a properly functioning lighting system on vehicles.
