Thanks for the suggestions, tsl. I try not to ride in the rain, but it is unavoidable at times, so I will heed your recommendations when installing the light.

I run my headlights and taillights while commuting in daylight as well as dark, which is one reason my the dynamo appeals to me. I'm looking forward to using it, but it might be a few weeks until I receive the light and wheel and get everything installed. The wheel is a custom build.
