They both appear to use digital accelerometers, thus the Maxxon's claim of using "Nintendo Wii hi-tech employed". I like the Maxxon. I like the auto-on, and I like the choice of flashing or steady. If I'm riding alone at night I like flashing, but if I'm going to be with a group, I don't want everyone to have to stare at my blinking light all night.

I think steady to brighter steady would work well, as long as it's bright enough. After all, that's what people are used to seeing car tail/brake lights do. If you're following something with a red light on the back and it suddenly gets brighter, the automatic reaction is that it's a brake light.

One thing that turned me off to the Lucid light was this claim "Most bike to bike accidents happen because the guy in front slows or stops and the one behind doesn t notice in time.". Funny, I've always heard that most car/bike accidents happen at intersections when one unexpectedly turns in front of the other. I've also read that rear-end car/bike collisions are fairly uncommon. My experience goes along with that, too. It just kinda turns me off when an advertiser claims a "fact" that goes against what I know.
