Patent Images
1. A vehicle indicator comprising:
- a persistent luminescent layer forming a trim ring extending around a fuel receiving port and configured to emit a first color of light;
a first light source configured to emit a charging emission to charge the persistent luminescent layer; and
circuitry configured to selectively activate a plurality of portions of the first light source, wherein the persistent luminescent layer is charged and illuminates the indicator in the first color.

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.

8. A vehicle fuel level indicator comprising:
-
an indicator encircling a fuel door enclosing a fuel port; a persistent luminescent layer configured to illuminate the indicator in a first color; a first light source configured to illuminate the indicator in at least a second color; and a second light source configured to sequentially charge a portion of the persistent luminescent layer in a second color, the portion corresponding to the fuel level of the vehicle. - View Dependent Claims (9, 10, 11, 12, 13, 14)
