I just spent the day installing a Brightasslights Bal-T3R. It fit almost perfectly on the mounting plate that holds the reflector clamped to the luggage rack. It's pretty bright with many flash pattern options and makes my stopping much more visible compared to the wimpy taillight. Since it only has 3 bright LEDs it's not quite as bright as the taillight I had on my Harley from the same company. Still, all in all it's not bad. I don't seem to be able to post a video, so I guess a crappy picture will have to do.
As long as I'm logged in, how do you post a video???
