Flashing 24 hours a day, seven days a week, our Solar Stop Beacons are the most advanced 24-hour solar stop flashers on the market. Whether in congested cities, or on rural and remote roadways, K&K System’s Red 24/7 Solar Stop Beacons are used to enhance the visibility at Stop, Do Not Enter, and Yield signage. In the past, stationary stop sign 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. The 24/7 Solar Stop Beacons can be configured to run anywhere in the country.
