Let me introduce our patent adjustor to you.
1.The dial of adjustor can be replaced with LED light, l would like to send you a LED light for free, you can show it to your customers, if they are happy with the LED light, then you can sell the helmet and LED light separately in near future.
2.If the adjustor will get broken after using a long time, then the user can change a new adjustor by themselves, fully DIY. So you can also sell the helmet,LED light and adjustor separately.We also have other led light helmet.
3.Below are the pictures for your reference, you can try to detach the adjustor by yourself, and try to change the LED light, It is a very good advantage which can help you to expand your business. :) hope we can build a long-term business relationship with you.
