Hmmmm...shortly after I started using one, a co-worker told me that the light was quite noticeable from about 100 meters back. At the time, I was riding eastbound and the sun had only been up for 1 hour.
I agree it's not as visible as some of the high-wattage, high-$$ units, but for the price it's a really good accessory. I run one on the seatpost, and one on the left chainstay, and usually run them day or night.
