I think they're annoying as helk, but they sure do get attention. I'm not sure how you'd get it to stop after so many blinks, but you could have it constantly blink by putting a flasher in line to that light. It's the same concept as your turn signal. Just get one with a very low amperage rating so that it doesn't blink really fast and you're good. It'd be snipping the wire, putting connectors on each of the ends and connecting it to the flasher. Very simple.
