Kudos to invisiblehand for understanding the spirit of the question. This is just generally speaking. At night. Forget the variables for the time being.....other than you would be on a some kind of road with traffic. And this is not about whether or not I would buy a specific kind of light....rather a poll of yes or no. Humor me. I'm trying to get a sense of what the consensus might be just from the question as it stands.....without all the analysis (I've seen plenty!).
If you feel you can't submit a tangible and definitive answer from the criteria given, then refrain. It's not that big a deal. :-)
