Review on Warning Sensitive Flashing Barricade Construction by Joshua Garris

This product works exactly as described. It's bright enough to be seen at least 1000 feet from where I can see it. It lights up at the perfect time of day when the blue light in the sky makes shadows and other objects in darker areas difficult to see. One charge lasts for several days. I only give 3 stars because 1) there is no switch. It only turns on and off in daylight and there's no way to control it. Very annoying when it's waiting to be installed indoors and 2) when it's in a northern area where there is shade most of the time in winter or when days are mostly cloudy, the charging console isn't big enough to get enough power to get charge properly. Therefore, there is less visible light that does not last all night.
