Abstract: The portable illuminated real estate sign system consists of a carrying case, a sign, and a post. This solar powered illuminated sign is attached to a detachable post that has an anti-theft device. An accompanying bag is used for ease of transport and storage. The sign can be single- or double-sided, having a weatherproof casing, a plastic transparent front and back, and a hinged door to allow signage to be easily changed. Within the sign casing is a solar panel that collects solar energy to charge at least one rechargeable battery, energizing light sources to be turned on by a light sensor from dusk till dawn.
