I finely installed a brake light signal module from Signal Dynamics Corporation. It is called BACK-OFF XP. There are two ways to wire it to your center brake light.
Mode One - 4 short flashes and one long flash for about 10 sec., then it repears itself.
Mode Two - 5 short flashes then steady on.
I used Mode Two. Now the cars in back of me will notice me better. The system I had on my bike worked great. There is also an optional back up flaser. This causes the center back up light to flash when you are in reverse.
