I wanted to bring up a concern I had today when riding behind my friend who has recently purchased an F6B (I'd love one myself, but it's not in my budget right now). The stock brake lights don't really seem to do much in the daylight. I'm not sure about how they look in the dark, but I didn't think they were very visible. We were riding with a group of various bikes from different manufacturers and the F6 brake lights were the least visible of the group. I know there have been several different options discussed here and would like to encourage you guys to at least consider taking a look at doing something to increase visibility from the rear when braking. I know we don't often know how our bikes look from behind when we're riding them, but I was a bit surprised about this, given that most everything else on this machine seems so well engineered.
