DOSUN began by the faith of guardian in the night. We believe the cycle lights plays an important role to cycling activities.

DOSUN is dedicated to developing high quality cycle lights and reflectors based on cycler's experience and unsatisfied need.


You could also find DOSUN spirit from our brand name "DOSUN". The logo's idea comes from the connection of human and lights.

We believe the science and technology throughout comes from the human nature.
