........I've been playing around with LED strips. These strips are powered by a 12v battery, but I recently noticed that they can also be powered by a common 9v battery as well. Although 9v batteries dont have much capacity (only 280mAh) they are much cheaper and smaller than 12v NiMH packs that are soldered together. A pair of LED strips are about $10, 9v is $5, 9v charger is $2 on ebay and 9v case is about $3 from Radioshack which brings the grand total to $20.
........I just purchased a rechargeable 9V from ebay and will provide an update on its running time. Has anyone else used LED strips? I think their great for side visability when attached to the down tube or top tube.
This pic does no justice. I will have to take another when it gets dark out.
