When the lockers are ingauged = it has a seperate light in the switch. The illum lamp hook up is so ya can find the switch at night. Two different bulbs in each switch. 3 switches = when lights are on it has a small line lamp, 1st pic. when compressor - front locker - rear locker = what ever is on,the big square light is alluminated. 2nd pic. So with the illumination after the dimmer I will be able to control the amount of blue light glare I get in my face. Very kool set up I think, You?

However I might be wrong about the on lamp being controled by the dimmer, I am sure about the line lamp being able to be controled by it. Will know more once all back together.
