Hello, guys...I happened to find this post that talks about the brake light (maxxon wireless brake light) made by our company. By the regulations of this forum, I am not supposed to say much about our own product to avoid the allegation of advertisement, but I do have a question to consult with you guys. Actually, other than wireless brake light function, our light is also equipped with so-called "stable brightness across even in low voltage" function by PWM/SWITCHING controlling techniques, which makes the use of rechargeable batteries (2.4V, not 3V as regular batteries) without sacrifice of brightness. Does anyone of you guys consider the function useful or valuable to you? your kind comments/ideas will be appreciated !
