I third the SureFire recommendation. I am a friend of the VP of Engineering there-Paul Kim; better known in flashlight circles as PK. He started a spin-off company called ICON. ICON has all the design power of SF; yet is sources the lights in street friendly colors and themes from Asia. No Olive drab or biker black from ICON-as is the case from Surefire. So there are some really cool ICON LEDs that PK is continually introducing into the market. Real bargains considering who is behind these:

Note: several USA dealers are selling these at good price points. Costco even sold a 3-Pak of the ICON Rogues a while back.
I have 1/2 dozen of these Icons in various models. Cool stuff. I've been a CPF member for a good 6 years or more. It can **** you in. Yes I am a flashaholic.
