In 2012, a customer contact us that they want to develop a LED belt, which 
can give a good visibility to people when they do sports in dark night. We 
Tried some times but failed. Customer almost give up at that time. We asked
Cutomer give us one more chance. We just want one more try. After 3 days,
A new belt came out. From then we worked together with customer to make
The HALO belt become a famous brand.
