Stupid question but why does the flag need to come down every night (or be lit)? Is this a rule across the board, so if you had one at home it also has to come down?
From an American Legion website on proper display of the flag:
§ 6. Time and occasions for display
(a) It is the universal custom to display the flag only from sunrise to sunset on buildings and on stationary flag staffs in the open. However, when a patriotic effect is desired, the flag may be displayed twenty-four hours a day if properly illuminated during the hours of darkness.
In my opinion the most flagrant violations of flag etiquette are these:
§ 8. Respect for flag
(d) The flag should never be used as wearing apparel, bedding, or drapery. It should never be festooned, drawn back, nor up, in folds, but always allowed to fall free.
(j) No part of the flag should ever be used as a costume or athletic uniform. However, a flag patch may be affixed to the uniform of military personnel, firemen, policemen, and members of patriotic organizations. The flag represents a living country and is itself considered a living thing. Therefore, the lapel flag pin being a replica, should be worn on the left lapel near the heart.
