this is the part i do not understand..why do you want MORE flashing lights?
you already have blinkers...of two colours.some red, some amber..the flashers
are would be hard to follow...that is why i suggest a setup with rows..so
that..at normal braking..the top row lights up..showing much like a normal
light..then, if you jack up the pressure in the brakingsystem above that,
another row lights up..making it brighter, and slightly different in appearance
so that (hopefully) the driver will notice something different and react...
and so on until lock up(non ABS) at which time, the whole think would start
over......i dunno..still thinking about it(but not too hard...)i just cannot
figure out why you would want more BLINKING lights.....
