I actually have two 1AAA clickie lights, but I can't recommend either. One is marketed my Illinois Tools and I found it in a Ace Hardware bargain bin for $5. It has 3 LEDs and a regular (not reverse) clickie. However, it is really dim. The other is the Shorelite Vx-1. It has a side mounted electronic switch and four levels which you must cycle through. Very unique and fairly bright, but the beam is very splotchy and blue. I've never seen the first one again (Craig may have reviewed something very similar), and the Shorelite may still be available at GlowBug.
