Stem-integrated bike light stays onboard and unobtrusive

Headlights are essential for night-time bike commuting, but they can also be a bit of a hassle. Among other things, they can get stolen (unless they're "theft-proof"), you might forget to bring them, and they can clutter up your handlebars. British product designer Anirudha Surabhi Venkata set out to change that, with his stem-integrated Lumineer light.

Putting it simply, the Lumineer is an aluminum handlebar stem with a 300-lumen water-resistant LED headlight built into its unibody front end.

Its tilt angle can be adjusted via its two mounting bolts, while riders turn it on/off and switch between modes by pressing on its lens. Power is provided by a removable rechargeable 3.6-V/2,500-mAh li-ion battery, located in the main stem. One USB charge should be good for up to four hours of steady high output, 15 hours at "pulse," or 70 hours at a 50-lumen flash setting.

Venkata, who previously brought us the Kranium cardboard helmet, is now raising production funds for the Lumineer on Kickstarter. A pledge of £50 (about US$72) will get you one in your choice of two sizes and two colors – chrome or black – when and if they're ready to go. The light is demo'd in the video below.

And should a stem and headlight combined in one device not be enough for you, you might want to check out SpeedX's SpeedForce, which throws a cycling computer into the mix. Helios Bars likewise feature integrated lights and "brains."

The side view of the video start frame shows it pointing upwards with the re-touched light with an asymmetrical light pattern slightly downwards. With the light reflector being inline with the handle bar extension it will inevitably point upward and be a see me light for aircraft... Maybe slope the reflector or lens more horizontal and slightly downward or at least address the alignment issue somehow with an adjustable front end.

Its tilt angle should not be adjustable and kept at a legal downward angle at all times?
