Multiple LED's on separate pins, switches and functions - need guidance

I set the non-signaling tail light to 255. This is the best I could think of without using a separate strip of lights to indicate turning and braking separately. The light strips are about the same width as the forks on the bike, so a second strip would be mounted on the side of the forks. And If I was doing that, I'd just go back to mechanical control rather than software control with the arduino. What should I have done differently?
