Since backlighting is such an awesome feature, most of our customers want to have all the switches backlit for night readability.
Backlit for night readability
To do this we add a second light to the switch and move the indicator light to the bottom. Now the top light can be triggered by any switch
Top = backlight
Bottom = Indicator
The backlights lights can be triggered by any switch. Usually the Nav lights, or (as in the case below) a panel light switch.
