ALLIGHT - Always Level Light
Smart motorcycle lighting
Allight Systems has invented a smart, motor-controlled motorcycle light for the aftermarket. You can replace your regular H4 bulb with this innovative new product, which ensures that the illuminated area is always optimal, regardless of the motorcycle's inclination in the curves.

The light source is suspended in a kind of active gimbal that uses a precision motor to keep it level with the road at all times. Lundinova has developed all the electronics, motor control and software, which together with control algorithms ensure that the light source always remains horizontal. The algorithm turns out to be quite complex when you zoom in on the problem, it is not just to measure the gravity vector with an accelerometer, a motorcycle creates large dynamic forces that must be considered, not least when cornering.
