You know, I feel like an idiot for not looking to see if I can use the clip on the blinkie (planet bike superflash, I think) when I have the trunk on and the post bracket when it's not. I'll have to look to see if there's something I can clip it to on the post. Maybe I'm overdoing things since I ziptied another bracket for another of the same blinkie to my helmet, but I just want to make sure I'm visible. I do have that (not so useful but can't get rid of because my wife thinks the turn signals are essential) light already on my rack and I don't really have room for another because of where the fenders are and panniers attach. If I used the rack/panniers all the time I'd be fine just permanently attaching the light to them, but this is my one bike for everything so I want to ride without them but with the light sometimes.
