HELP ME PLEASE - REGION SWITCHING QUESTION(S)

[midnightresistance]

I am about to embark on my first region switch mod for my md1 but i have an idea about linking an led to each region when they are in the relevant position to show which region the console is set to (as well as the position of the switch)

so my question is - HOW? or IS IT POSSIBLE?

i.e

uk or standard position - red
jap - green
usa - blue

meaning that when the region is set then only the relevant led is lit

also does anyone know where i can get suitable SPDT rocker switches?

thank you in advance and anticipation.
