More info on my brake light flasher.

I bought it on e-bay from china for about $4US. It is called GS-100A Strobe Controller for LED stoplight. You simply splice it in line with the stoplight wiring. I did mine under the seat between the ECU and the light. When you apply the brake, the LEDs quickly strobes for 0.6 sec then flashes for 3 seconds and then steady on. The effect is great, if this does not get their attention, nothing will.
