Meet Speednite: a lighting stem for bikes that you can control using head movement. It features tilting headlight and laser direction indicators. You get a small head motion sensor that attaches to your helmet to allow you to control the light with gentle head movements.
Speednite’s headlight has a max vertical movement angle of 130 degrees. It has 800 lumens of light, so you can see well at night. Expected to ship in as early as October.
