For those keen in electronics this should be easy to assemble, for others - ask a friend who is
Adjust schematic (values) as it fits your implementation.
12V input is meant as Clearance lights input or other backlight source. With it on, switch LEDs will be on with low brightness, so that you can see their location in dark. When switch is activated, then they will be at full brightness.
Also there are 2 active-low LEDs for some warning and such, like Check Engine Light and Traction Control active. Can be controlled by AUX output of ECU.
Disclaimer: design is presented as is, and I do not take any responsibility of damage, if any, caused by it.
