The rear is set on blinky since I can't see the cars coming fast behind. Other lights are set solid because I can see the cars so I prefer them to think I'm faster than I really am (I look somewhat like a motorcycle) and blinkers are just downright annoying (for me and them).

This is for my commuting bike. If this were for a light road bike with "just-in-case" lights, I'd probably go with front and rear blinkies.
