I ran into, not literally calm down, a local on a bike that I have seen riding every night but never been able to stop until the other day. He runs a Cygolite head light on the handle bar, and rear and then has a set of smaller Cateye lights on his helmet (white front/red rear)
All I can say is the ONLY reason I wanted to try to chat with him for months was he stands out COMPLETELY above all the car traffic around him. And was a nice guy too!
