Solar-powered traffic signs

Lintec is marketing in Japan solar-powered traffic signs that have no electric wiring and consume no electricity. The sign stores solar energy in the daytime and automatically illuminates when it gets dark, remaining lit until dawn.


Using a white LED as a lighting source, the product can be used for 10 years, company officials said.

Lintec expects the product to be in demand for use in rural areas where power-supply services are not available, such as in the mountains.
