Another thought: Fenix Digital L2D Black Premium Q5
For 1/5th the price of a cateye triple shot. I don't know how bright the cateye is, but the Fenix is AWESOME! I use it for night riding on city streets and night trails. On the city streets, the lights do not get washed out and I feel that I can see well and drivers CANNOT miss me. On the trails, it's like riding in the day, it's THAT bright!
