The bottom line is what this article states: "You Have No Excuse Not to
Bike with a Light, Day or Night."

Except that on a sunny day most nearly every bicycle DRL is TOTALLY INVISIBLE compared to the bicycle + the rider. Heck at night I've seen bicycle bright red rear lights vanish from viwen in a queue of car lights. DRL for a bicycle might be useful on a dull or overcast day or in other dim light but they are NOT all that useful in bright or full daylight light. What's worse is that many who do use a DRL have a very false sense of security because they think a driver will see their light when in fact most lights are not bright enough to be seen easily in daylight and are only seen well AFTER the driver has seen the rider on the bicycle.

Do you get a kickback for selling DRL for bicycles?
