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.

Cateye EL320 With a single 1watt LED powered by four AA batteries (included), the EL320 is a simple & compact unit that offers up a nice balance between enough light to see where you're going & a good amount of visibility. As with a lot of LED lights, the brightness at obtuse angles isn't as good as some filament units, but the addition of two little 'peep holes' on the reflector unit helps a little for sideways light spill (handy for junction & roundabout visibility). There's no denying that this is a nice light in terms of striking a balance between seeing & being seen. The mounting is a simple-to-use band that's also at home on wing-shaped bars (so long as you have the wing part fl at on your bars). As is typical for every Cateye light we've ever tested, it burned way longer than they claimed, with nearly 24 hours on full power from four fresh AAs. Speaking of batteries, there's also a handy push button under the unit for removing them, & it's not until you have to change them that you realise how great this simple feature is. ...
