What must a vehicle's high beam indicator do to pass inspection?

For a vehicle to pass inspection, the high beam indicator must light up only when the high beams are on. This requirement ensures that the driver is properly informed about the status of the high beam headlights. If the indicator is functioning correctly, it will provide a clear visual cue, helping to prevent situations where the driver may inadvertently use high beams when it’s not appropriate, such as in the presence of oncoming traffic or when following another vehicle closely.

This functionality is crucial for driver safety and compliance with traffic regulations, as utilizing high beams incorrectly can cause glare and impair visibility for other road users. Thus, the high beam indicator's role is fundamental in promoting safe driving practices.
