On the way to work yesterday evening, a motorist thanked me. Apparently the flashing light on the front of my bike was visible over block away. He waited for me to get to the intersection he was waiting to turn left at until I was almost through it. Then he made a point to thank me for making myself visible, which was pretty cool of him. Considering many motorists don't see me in broad daylight, I was impressed that there was even one who could see me at night.
