Where do I put lights

[130fe]

I used to have a setup like that and put small green 1/4" LEDs in the bezel at the 12 o'clock position (when looking at the gauges). I bought the LEDs at radio shack, look for "built in resistor" ones, connect the factory wires (light blue, dark blue- forget which side is which) and ground the other. Works like a champ! This is what they look like- https://detroitspeed.com/Electrical/120901-leds.html
