If you want a top quality light for an excellent price, then consider our Cree Q5 UltraFire LED handlebar light for bikes & scooters.
This light is frankly impressive. Not a wimpy stamped-out piece of junk. The high quality machined aluminum battery case measures 3-1/2" long and about 7/8" in diameter. The flashlight itself is removable from the handlebar bracket.
There are three operating modes: super bright, normal, and a blinking strobe. You can focus the beam into a narrow point, or widen it for the most illuminated point of view. The universal handlebar mount is included, but the AA battery is not.
If you want the best, the most dependable and durable light, then this is the one you are looking for.
