An after-hours shop sign can also be referred to as a late-night store sign, a 24-hour establishment sign or a night owl shop sign. Other synonyms could include nocturnal store sign, midnight shopping sign or an all-hours business sign. These types of signs are usually brightly lit and highly visible, indicating that the business is open throughout the night or outside typical business hours. These signs are commonly found in cities and towns, where people may need to do some last-minute shopping or get something urgently outside regular business hours. Regardless of the name, the purpose of the after-hours shop sign is to let customers know that the store is open and ready for business, no matter the time of day or night.
