Originally, it was unintentional; I just wanted to keep them handy in case of a problem that would leave me walking, since there are a few places along my rides where I could safely leave the bike. (Friends' fields, etc. Might be a couple miles to their house to ask for a ride if I was passing their back pasture at the time of a breakdown.) When I went to get it out of the dark garage once, I noticed that they were the brightest reflection on the front. Plus they sit in that bend of the riser bars where nothing else mounts well anyway.
