We had a new road and it needed a few weeks to dry. We have these cones to mark our driveways. We didn't use the lighting function. However, we installed one of the lights and that made it more vulnerable to wind. Lights turned off again and no more problems. The only possible problem was that the color was fading. This is kind of understandable since the sun in Florida is very strong, but I want it to retain a bright orange color.
