A presence or an absence of an occupant is detected, and an occupancy sensor signal is generated representative of an active state in which the presence of the occupant is detected, and an inactive state in which the absence of the occupant is detected. An ambient light sensor detects the ambient light level and generates an ambient light sensor signal representative of the ambient light level. Dimmable illumination is generated at a first dimming level, based on the ambient light level, corresponding to the active state and a second dimming level corresponding to the inactive state. A transition delay time between an onset of the inactive state and a transition between the first dimming level and the second dimming level may be controlled. The first dimming level, the second dimming level, and/or the transition delay time may be variably set or controlled locally or via a remote device.

The solar-powered light for motorists on roadways is an electrical device. The solar-powered light for motorists on roadways is configured for use on a path of a multipath structure. This disclosure assumes that the path is a road. The solar-powered light for motorists on roadways mounts in the road. The solar-powered light for motorists on roadways generates electromagnetic radiation that illuminates the road when the road is in a period of darkness. The solar-powered light for motorists on roadways comprises a housing and a lamp circuit. The housing contains the lamp circuit. The lamp circuit is independently powered. By independently powered is meant that the lamp circuit can operate without an electrical connection to an external power source.
