I have the red leds for the front facing the driver, then I have the 10 other led buttons on the side facing the driver...
As for the flat piece facing down, I'm not putting buttons... I'm putting in some Cyberdyne Digital Gaugues...
Here is a template I had custom made to house them...
I'm legally blind... and cannot read the bar graphs (I can see the lights, but not read the legends)...
this way I can look up and see exact numbers for volts, temp, oil pres, fuel, boost and air / fuel...
