Abstract
A mobile sign with a solar panel for warning motorists of highway problems. The mobile sign comprises a wheeled vehicle, an electrically powered sign panel mounted on the wheeled vehicle, a chargeable battery for powering the sign panel, and a solar panel for charging the battery. The solar panel is rotatable and tiltable relative to the wheeled vehicle. The sign panel is independently rotatable relative to the wheeled vehicle. The sign panel has a low-glare, high-contrast display that also improves the lifetime of the display's electronic or mechanical components by reducing heating of the display due to the sun.
