I was in my LBS yesterday and couldn't resist the cute little Frog 1 LED red blinky light for $10. What I liked about it is that you can mount it around anything and it will attach easily w/ the rubber grip mount built right onto it. I also have a PB superflash but I think I'll pick up another Frog red blinky and that way I can put a Frog on each seat stay and use the superflash on the back of my rack. I also picked up for $6.95 a bunch of very reflective stickers that I plan to put on my rims, fenders, chainstays and top tube. So that's the $17 version of lighting up.
