i am making a fanbus for my computer and have made a basic diagram,

the question i have is that, does anyone know how i would put in 2 leds for each fan. one to light up when the fan was recieving 7v and one for when it is recieving 12v, depending on which setting the rotary switch was on. the right hand side of the diagram is for my cold cathodes so you can ignore that bit.
thanks joe
