Solar Barricade Lights – How ‘Proof’ Are They?

Sitting in my office today I can hear the trickle of the rain behind me, and it made me think, at what point is bad weather too much for solar barricade lights?  We all know they need a good amount of sunlight to get them started, but what about being too hot, or too cold?

Rain should never be an issue with a barricade light.  They are designed so that they do not let water into the important components.  The problem can be temperature, if it gets below zero where you plan on having them you may want to do a little bid more research and see if your lights can handle that temperature.
