This flashlight from Eddie Bauer is pretty nifty. The color is bright and changes by pressing the button so theres no lens switching. It comes with a cord handle, so you can create some means of making it hands free.
I've got a Rayovac with the pivoting head (found it at Walmart in the camping/fishing section). It has a clip on it and I just attach that to my shirt or whatnot and I'm good to go. It comes with a clear and a red lense that are interchangable. I just keep the red lense on the Rayovac and I have a MagLite for my other flashlight.
