How about this: flash briefly but very rapidly--say, 4 times in one 
second--but ONLY when the braking system fluid pressure exceeds whatever 
it takes to decelerate at 0.5G (exact figure open for debate...hopefully 
somewhere off this list!). After one second the flashing stops in favor 
of a solid light...or perhaps stays flashing if braking exceeds 0.75G. 
Whatever.

This requires no rocket science. In the '50s, Fords used pressure 
switches instead of mechanical pedal switches to actuate the brake 
lights, and ours surely weren't rockets! I presume they stopped using wet 
switches because they became more expensive and less reliable than dry 
ones.
