The HL-EL135 has three bright LEDs with Cateye's Opti Cube™ lens technology for a wider beam with excellent visibility.
It has a flashing mode if you are using it to make yourself seen by others & will light the road ahead on constant mode better than the less expensive models, so can be used on unlit roads to show the way. (measured at 60% brighter than the next lower priced light in Cateye's range.)
That extra bit of flexibility & power combined with up to 320 hours of run time makes the EL-135 an excellent compact commuter light.
The stylish, compact design measures just 2.5 x 3.5 x 9cm, which can be handy if you want to take the light off the bike for security at any time.
Includes: the Flex Tight bar bracket for rapid, easy fitting, & batteries, of course.
