As usual with these types of threads, most people recommend what they have, if they like them and it works. I run all Cygolite lighting (Expilion front, 2 Hotshot Pro 80's rear), and besides their performance and features, I highly recommend them because of their excellent mounts. They stay rigid, meaning the lights are always adjusted the same way every time you take one off and put it back on. I DO NOT recommend L&M lights because of their rubber strap mounting methods. In my opinion that's an extremely poor method for mounting lights to a bike.
