Easy install and worked great, but stop working maybe batteries. Easy to install, great idea worked great, but has stop working as a brake light might be batteries haven't had time to check. transmitter does interfere with my garage door opener, but not really a problem. November 28, 2015
works well works as advertised. but some helmets come with the light and you have to buy the rf unit. the price is kind of high for something like this. but for the safety aspect, it cant be beat September 14, 2015
Great added visibility When looking at the GMax 78 Helmet I thought it would be better to have the light working with the brakes. I felt like just having the light on, would increase visibility, but could be potentially distracting and people might then ignore the actual brake light, so this added some peace of mind for me. It was very easy to install on my GS500 by simply popping off the seat. I tried to find a wiring diagram to tell me which wire was which (+/-) I ended up unhooking a connector and using trial and error while sticking the wire ends of the transmitter into the female connections that lead back to the bike and tapping the brake to look for the light to come on. I tucked the transmitter box beside the brake wires and it was able to slip it under a zip tie that held the brake wires close to the frame so it won't be knocking around when I'm riding. During daytime it's not as noticeable but I think it is still an excellent improvement. May 4, 2015
Very easy installation The vents next to the LED are tricky to get off. Unsnap them from the bottom, then the top, then slide away from the LED. The wiring clips for the transmitter work, but they're pretty cheap. Might be worth getting some decent ones from a hardware store. As long as you have a wiring diagram to determine which wires are positive and negative to the brake light, it's super easy to install. September 5, 2014
Cool product I have not used this on the road yet but I'm looking forward to the added safety it will provide this riding season. My husband and my father-in-law also bought one each for their Victory's. We have tested them and are pleased with how they work. Installation into the helmet was easy. The bike a bit more complex for my Harley. April 16, 2013
It's ok. I purchased the GMAX GM78 Firestarter helmet and this light kit at the same time. I was a bit nervous to start tearing into a brand new helmet to install the kit, but I took my time and used care not to damage anything while installing the kit. Installation wasn't difficult. Took me about an hour from start to finish. It's been working flawlessly for about 3 weeks with no issues. My only complaint is with the clips that hold the clear plastic light cover on; they don't really snap too firmly in place. It's never come loose, but I still don't trust it. January 28, 2013

Al K asked: Hi, does anyone know if you can have two transmitters and pair it to one helmet light? In other words, if I have two bikes, can I put a different transmitter in each bike but only use one helmet and light for both bikes? Thanks! Mar 5, 2015

Christopher K: Based on the pairing instructions I found on YouTube, I don't think so. ("How to pair the Gmax Brake Light Kit")

But keep in mind that the LED light is not very visible during the day anyway. And if you want to switch bikes, it's a simple process to pair the light kit with the other transmitter.

Dwayne C: TWO TRANSMITTERS......NO! I have two helmets with the added brake light on them and I've tried to hook up both transmitters to my bike and work the helmets together and individually. One will not work Nov 6, 2015

A shopper asked: do you also have to buy the gmax gm67 battery case for this to work? Nov 6, 2015
Answer this · Send to friends Good question? Yes (0) No (0)
Dwayne C: Hello,

It all comes as one kit but NO you do not have to buy the battery case extra. The battery case you have in your helmet when you bought it has a white quick disconnect on it that when you unscrew the tiny screw on the top of the helmet and pull the battery pack out there is a white clip the wires connect to. It just pulls apart. there will be a white clip on the black n red wire also. Pull it out with the light then feed the new light wire in through the back of the helmet you then can plug the battery case into the brake light.
Hope this help you out.

Christopher K: The LED replaces the one that comes in the helmet. It adds an extra button press for brake light. The transmitter splices into the two wires that go to the brake light bulb/filament. (A schematic is handy.) The module is the size of a large relay, and it can go anywhere it'll fit. There was room under my pillion seat for mine, with easy access to the brake light wiring there. But I'm sure you could add length to the wires and put the transmitter somewhere else. Dec 17, 2014
