Speedometer & Tachometer

I purchase a 77 Corvette and there aren't any light bulbs in the speedometer and Tachometer just empty sockets can you tell me the location where they go?

if you see the empty sockets why are you asking where the light bulbs go?

I am not sure exactly what you are looking for, but below is a photo of the back of my 77 speed/tach cluster. The wiring is VERY non-stock (designed to make removal and servicing the cluster much less difficult) but I have preserved the GM color codes on the wires. The lighting is at the 2,4,8 and 10 positions on both instruments and is gray. The turn indicator lights are both at the 6 o'clock positions (left turn - light blue, right turn - dark blue), and finally at the 12 o'clock position, is the green wire (high beams) and the pink and brown wires for the brake warning light.
