For those considering going the flashlight route. For the past few years I've been going with the TerraLux Lightstar 300. $29 at Amazon. This with a two fish lock block to mount it with. And some good rechargeable batteries. And you've got yourself a good inexpensive (under $75 with charger) light. Excellent commuting light. Handles any weather thrown its way. I change the batteries after the third day. I've had Fenix's that suddenly quit after a few months. Same with Romisen. I had a romisen for four years before I replaced it with another one that lasted me one month. Never again. I've had the Terralux for two years and have had no issues. I have another one as a spare in the house. Rugged and well built. Made in the USA too.
