Anyone has seen the "down low glow" lights?

[pll]

A rider in Evanston has this very visible green light under her bike, which illuminates the area surrounding her bike and also let's you see the bike. After seeing the previous post about being afraid on commuting in the dark , I "googled" and found it is called the "down low glow":

It definitely catches your eye while driving a car. Anyone here use it?

On an unrelated issue, a quick rant: Evanston painted some bike lanes on one way streets at the end of October and now I see more cyclists, no helmet nor lights, riding against traffic in those lanes (there are also huge arrows painted on the lanes, so it should be evident to anyone that they are riding against traffic)!! Needless to say, I have already seen dangerous encounters where drivers do not expect someone against traffic at crossings.
