The START button lamp on RACE RIOT is extremely dim. (It is hard to 
tell if it is on or not.) the Mail message below describes the 
problem. The 2N3904 solution is not significantly better to be a 
complete solution. I recommend that the lighted buttons for STEEL 
TALONS have 12 volt lamps, and be driven from 12 volts instead of 5 
volts as is currently planned. Any Comments !
