As an avid TV watcher during my childhood, I still have the song "Weebles wobble but they don't fall down!" in my head. That concept came back to me in a wave of nostalgia when I saw the Wobble Light. Based in Illinois, Wobble Light has developed an innovative way to provide consistent lighting in a high-traffic construction area. The unit is weighted specifically to right itself on impact and a floating shock system prevents the light bulb from being damaged. In addition, an internal ventilation system keeps the unit from becoming as hot as the sun. When a collision happens, the light source is preserved and the person who ran into it isn't burned (ever walk into a lightbulb that's been on all day? It's an experience you won't forget!). The unit can be set to provide light in a 360 degree radius or focused on a particular area with a set of blinders. Prices vary depending on the wattage, but expect top pay between $150 and $250. It is available for purchase at most large retailers.
