Some of you asked about the flashing lights I had on my tripod legs at Pixelmania. To be honest, I copied the idea from Joanie. The lights I use are available from Kikkerland, but I bought them locally (possibly at The Container Store). Each package comes with a red and a clear light, so you have to buy three packages if you want a red light for each leg. They have an elastic loop which can be slipped over a tripod leg. There are three light modes: slow flash, fast flash and steady. They are powered by two CR1220 lithium button batteries which can be replaced by just prying open the case.
