I guess then there is no issue with the fact that our tail light bulb sits vertical. I have a flashing LED bulb I used to use on another motorcycle that had a horizontal bulb, and it worked great, but the LEDs don't show well mounted vertically. Of course, I guess this is a bit different, and I guess the position of the bulb should not affect it.
As far as people not liking the flashing light, tough $hit - I think they really make people notice you instead of look (and run) through you!
