A little heavy for a helmet-mounted light Loose Helmet Mount I use this light for early morning commutes. On top of this, the charge only lasts about an hour, it takes 9 hours to charge, and there are all sorts of warnings about over-charging and letting the battery run too low. The Cateye is a great little product. It can also be clipped onto a helmet.
The newer one which I believe is now actually discontinued is really bright. I can put two of them on my helmet and get some good light. It also has a flashing mode, and the batteries last a long time. Unfortunately, there is no way to tell if the batteries are running low. Also, two of them get a little heavy. And the rubber strap used for mounting is difficult to adjust.
On a handlebar, the thing never stays pointed in the right direction. So I decided to spend a little money to get something that would be brighter than the Cateyes and lighter than the Trail-Rat.
The Expillion is really a great product. It feels solid with a lot of metal. It is nicely sealed against the weather. It has a helmet mount. It has numerous modes in different brightnesses and flashing patterns. I use a mode that is the second brightest, with a flash interruption every 2 seconds. It gives me a relatively constant beam to see, it saves the battery, and it gets the attention of motorists.
As a helmet-mounted light, it feels a little heavy. After an hour of riding, my neck does get a little sore. The helmet-mount is a plastic bracket on a velcro strap.
The strap is a little floppy, so the thing will rock back and forth on the helmet. Also, there is a screw adjustment on the side of the light, so the beam can be aimed up or down to suit your riding position and visual preference.
The other nice feature is that it has a snap-lock release, so I can leave the mount on the helmet, but take the light off. This way, I can take it off the helmet for the commute home, and avoid the neck soreness. Similar Products Used:.
