@goride, that's a great idea! I'll check for those. I didn't see any at the grocery store.

@kmehrzad, I saw some fishing plastic holders for fishing licenses at REI. Great idea too.

I think I'm all set. I have a superflash blinky on the back of my bike (off the rear rack), but there is a strap across my saddle bag for another. I don't ride too often at night, but that might change as it warms up and I'm riding more. I think I might get another one.
