GMAX LED Wireless Red Brake Light Kit for GM 54, 67, and 78 Helmets

Despite what you'll red on other sites about having to order the battery box for the ^67s helmet, my light arrived with the box. Things to note: the insert on the helmet that you take out (to make room of the light) has two parts--outer and inner--take them both out! And after you put the light in, slide the side vent arms atop it, and then snap them in. I rated this 4 stars because the installation instructions were non-existent, although if you search on YouTube, you can find find how-to videos.

i bought the Gmax helmet and then this kit for the light. the light goes in the back of the helmet and i loved it. lights up good at night. the light in the helmet last one day. i called J& P and they sent me another one the same day free. the light has a sending unit that connects to the brake light. at the time i was putting on a LED brake lamp and the sending unit fit right in the lamp with no problem. i give the light a 3 but i gave J%P a 5 star for service.
