Very wet. I didn't feel like waterproofing my son this morning for the ride to daycare so we took the bus. Unfortunately we just missed it and stood around for 20 minutes in the rain. Shoulda rode. About 8C/48F for the ride from daycare to work. I have to give a big wet thumbs down to the Planet Bike 1/2W Blaze headlight. It is not waterproof and my RMA replacement is now waterlogged. That's 2 units that have not survived a Vancouver rain storm. I'm glad it's not my main light anymore, but still upset. Who designs a bike light that's not waterproof!
