What is the CA DOT certified pattern? Since you've got a Signal Dynamics box, I'm guessing it's the other pattern (from the one I'm using - 5 flashes then solid). In NY, I'm pretty sure the brake light is supposed to be solid only, even though the official drivers manual recommends flashing your taillight when stopping. Go figure ... bureaucrats.
At the end of the day, I'll do what's safest for me and I'll worry about the cops when the time comes.
