I LOVE those lights! I had one on my bike and recently lost it. Either it was stolen from my garage or I knocked it off myself at a rest stop and didn't notice. Either way, it's gone and I miss it terribly. It lasts for a long time on one set of batteries and has a very sleek design. I bought a new lamp with more lights built in so that 2 can be set to flash and 2 on constantly. This is a nice feature, but the lamp is so bulky that I wish I had my old lamp (like yours!) back.
