Abstract
An indicator disposed proximate a fuel port of the vehicle is disclosed. The indicator comprises a persistent luminescent layer, a first light source, and one or more circuits. The persistent luminescent layer is configured to emit a first color of light. The first light source is configured to emit a charging emission to charge the persistent luminescent layer. The one or more circuits are configured to selectively activate one or more portions of the first light source such that the persistent luminescent layer is charged and illuminates the indicator in the first color.
