ask for money back… u got a defective light.
If you check posts starting #6 in the link below, perhaps you could try this, I did it to my HO3 and now it works. It’s worth a try.
I am very glad that it is solved, for you. But this forum is not only meant for solving YOUR problems. Why would you deny us your learning experience?
This post was not going to help or teach anyone anything, it is a problem that left Skilhunt and an Aliexpress seller in a bad place and that was solved, nothing more, there was no a miracle procedure in this post.
You should edit your post because I am not DENYING ANYTHING TO ANYONE
