Thanks for the useful advice, Stepfam. A headlamp would never have occurred to me, too geeky. I always try to minimize the extra stuff on the bike, and I had always thought that headlamps were kinda goofy. They're great for cross-country skiing at night, though; in fact, one time at Silver Star ski resort (middle of BC), I was skiing back to the cabin for dinner when the entire Swedish womens' Nordic ski team skied by the other way, all with their head lamps. Actually, I wasn't really noticing the head lamps...

Good to know there is a use for head lamps. Thanks!
