Flashing 24 hours a day, seven days a week, our 24/7 Hazard ECO Beacons (warning lights) are the most advanced 24-hour solar flashers on the market. Whether in congested cities, or on rural and remote roadways, K&K System’s Solar Flashers are used to help warn vehicular traffic to possible hazardous areas or intersections ahead. In the past, stationary beacons were powered by utility grid power. In areas where power was not available or too expensive to install, traffic engineers have learned that solar power can be a great benefit in providing a reliable power source with no monthly power bill. 24/7 LED ECO Hazard Beacons can be configured to run anywhere in the country.
