The ultra bright red light on the HARD system is bright enough to give a person a sun burn!
Geez, if that thing doesn't catch your attention nothing will. I'll never get another speeding ticket as long as I live while I'm riding my Triumph, but I might drive right off the edge of the road and crash into the parked State Trooper.
Overall, I'm pretty darn happy with the HARD system but I have four comments:
1) It's NOT (it's really, Really, REALLY NN-OO-TT!!!) waterproof. I wouldn't expect to go scuba diving with the thing but it should be better protected against moisture than it is.
Which means that you can not mount the light unit to the outside of you helmet, which leads me to say......
2) It takes up more space on the inside of a helmet than most of us are willing to give up. No big deal but..., bummer!
3) You have to turn it off every time you take off your helmet or the battery will die. Conversely, you have to turn it on every time you put your helmet on or you won't know if/when the radar detector goes off. Double Bummer.
4) In a perfect world it would convey more information than just On/Off. Too bad it can't somehow be more like the Smart Cord on a Bel or Escort radar detector.
Overall, I'm happy with it and am glad I bought it.
