I saw a couple of comments in posts about flashing rear brake lights, and thought I'd throw a link up from the superbrightleds.com store.
The part number is 1157-R3W-FL.
I bought two of these flashers for my Honda CRF230 and Honda VTX 1300. On a whim, I pulled the one out of the little Honda tonight and did the 2-minute install on Barney. It works just great. Here's a 10-second video of it.

The light costs $18.95USD plus shipping from St. Louis, MO. (Shipping was about $4.50 for one to Virginia.)
YMMV --
