[6pack] Overdrive controller

[oliver]

i have on my car a light (yeah - another idiot light for another idiot) that 
is on when the od is engaged.  it helps, but its not nearly bright enough. 
its great at night, but with the top down on a sunny day, well . . .  i 
think a bright led might be a better idea.  its just wired in the circuit 
with the od.
