Most of people would have lights and locks for their bicycles to ensure the riding safety and parking security. As the lock may cause inconvenience while riding, which may be found that, the lock has no place to be placed when riding, so we decide to put these two major accessories, light and lock, together. Therefore, Safelight is the solution for riding safety and parking security. It becomes the rear light when users are riding; it becomes the lock when users park the bike. We improve the problem in an efficient way. Also, it improves the values of light and lock.
