I'm still riding the road bike to work, even though it's now mid August. I've got "be seen" lights on, including a blinky headlight. It really lights up the reflectors, such as those in these Bott's Dots. Actually, it gets a little hypnotizing and is worse than useless for actually seeing hazards in the pavement. In dark areas, I turn off the blink and run it in steady mode.
