If a flag is displayed 24 hours a day, what must it be during hours of darkness?

When a flag is displayed continuously for 24 hours, it is important to ensure that it remains visible and maintains respect during hours of darkness. To achieve this, the flag must be illuminated. Proper illumination not only honors the flag's symbolism but also adheres to flag etiquette, which states that it should not be allowed to become obscured or disrespected during night hours.

If the flag were to be removed, replaced, or folded, it would not be displayed in a manner that reflects the respect and reverence due to the national symbol. Therefore, illuminating the flag during the night ensures that it remains an appropriate and respected emblem at all times.
