Sounds like Dinotte might not be appropriate for a dark trail, but is appropriate if you bike down an unlit highway (for distance), or for commuting through NYC-style traffic and lights, or for daytime. Also appropriate if you are biking solo.

Of course if I bought it I wouldn't feel the need to justify it to anyone, even the irritated bikers who are riding behind me. Just like if I were "blinded" by a Dinotte while biking, I would either pass the guy or take a new route- but I wouldn't blame him for trying to be safe.
