The Niterider Trail Rat is a reliable light, but if you can afford the 15watts v. the 10w, you'll be much happier in the long run. Plus, if you do ever decide to do offroad night riding, 15watts is what you'd want as a minimum.

While I've never used a Jet light personally, I've contacted them many times on behalf of customers when I used to work in LBS, and they offered far and away the best customer service of all the light companies. Oh, and I was always calling for spare/replacement parts, never for repairs.
