For aesthetic reasons, I would want the blue. But, y'all are talking about the light creating problems with your night vision. Regardless of the color, I wouldn't want anything that bright. Just enough to make out shapes. As it is, it is pitch black in the footwell, can't see a thing. And, I'd like it on whenever the headlights are on. Not confident about tying into fuse box though. I'm a wuss, I guess.
