Cool idea FT!
I found a bicycle safety light from "Bell" that is just about the size of a credit card - about $8. It doesn't have the 2 rows of lights I'd prefer, but I'll try it.

It has 6 different flashing modes and may work pretty good for this low-budget project. I'm not doing this project to sell anything, just a do-it-yourself idea.
I have transparencies printed out and will put them together with the LEDs and the armor tonight. I'll post photos tomorrow.
If you have Illustrator 3 or Photoshop, print these on a transparency, There are several printed on one page in case you need to layer a few to mask the lights...
