I was travelling west on I-4 behind a Lincoln and every time he hit the brakes, the high mount brake light flashed, like on some motorcycles. Is that an option or a problem in the wiring? It caught my attention.
I have seen that on a few cars, and even motorcycles. pretty easy to do. either an inline flash unit , or a flashing bulb, that has the unit built in http://www.morrowmarsh.ca/concours/techpages/brakeflasher.htm
Howdy, I think that was started in the 2002 model year of some cars. JC Whitney sells this add on relay, "Brake light pulsator" #AGM060065X - $19.98
