A reflective pavement marker for a roadway includes a body having a bottom adapted to be secured to the roadway and at least one a reflector on the body. The reflector includes an outer face for receiving light and an inner face comprising a plurality of light reflecting elements for receiving and reflecting the light back through the outer face. The reflector comprises a light transmitting and thermochromatic polymer adapted to transition at a predetermined transition temperature so as to change the color of the light reflected by the reflector depending on the temperature of the polymer. The predetermined transition temperature can be selected so that the color change of the light reflected by the reflector indicates freezing or near freezing road conditions.

A modular system of light strips is configured for use on a roadway surface. The light strips are configured to withstand vehicular traffic, such as passenger cars, trucks, and even heavy equipment such as found in a construction zone. The light strips have a rigid, durable housing that protects a series of LEDs within the housing. The LEDs are preferably positioned fully within the housing, with lenses directing light from the LEDs through the sidewall of the housing and toward vehicular traffic on the roadway. The channel is filled with a protective material, such as a polymer resin, for example a polyurethane resin, that serves to protect the LEDs and power supply running within the channel. The modular system can be provided with a power source, such as solar panels, or alternatively configured for connection to a power grid. The modular system can include one or more sensors to activate the system or alternatively to control the brightness of the lights in the system and be configured with light strips that connect together or can be substituted for one another allowing them to be interchangeable and easily carried, moved, installed and disassembled.

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.
