I've had Hyper lights on the rear of all my bikes 3 or 4 bikes over the last 5 years (and the back of my SUV).
Between my bikes and my friends, I've never had a failure of the module or lights, my friend did have a failure of half the 16 LED light assembly which Hyper lights replaced without question and had them in the mail before he took his off... Excellent customer service..
With that said, on my FZ, I have the combo running/brake light set up. I have it mounted just above the tag. As there's only one stock rear running/brake light, this backs it up 100% should you blow the stock bulb. I also have it set up to blink constantly when the brakes are activated.
Its not diffucult to wire at all and comes with "Posi taps" for tieing into existing wires without any hacking. I have them tied in under the left pod near the wire junction
As a quick side note, there's few wires to hook up. When they want a separate wire to power up the brake light, you can just tie that to the running power light wire and save one connection...
If you go in "my garage" here on the forum, there's a picture of the Hyper light attached to the bike. Also, IMHO 2 16 bulb LEDs are too bright.....
I can't speak for the other brand but the Hyper light is considerably brighter, running and brake light than the stocker.. (2-3 times)
5-17-12, here's a picture of the 16 LED mounted up. I made an aluminum bracket that bolts between the tag and the fender with a 90 degree bend that the LED attaches to. I also moved the reflector up just slightly to clear everything..
