I got an llbean one just like that one for christmas one year, it works well but its a white light and I want red. I had my wife paint the lights with red nail polish, but it seemed to only dim the light and not really make it red...
I think the cap clip light is the way to go, I used to have a nice red one that I used for a couple of years then the clip broke, thinking about getting another one.
here is what I'm talking about
