ABSTRACT:
Self-contained solar-powered long-life intelligent illuminated road markers are provided comprising a one-piece housing formed of optionally colored plastic capable of transmitting light. Light is reflected by reflective coating or generated internally by LED which is powered by a long life battery, the charging of which is controlled by electrical circuitry which comprises a peripheral interface controller. The electrical circuitry provides intelligent control for a variety of modes corresponding to diverse driving conditions, and can enter a low-power sleep mode to conserve battery life.
