Dim Dash Lights

The rallye dash has only 4 illumination bulbs in a straight line across the center. 2 middle ones are so close to the center pod that half the emitted light can be blocked.
With a white plastic blank in the center pod, some middle light is redirected. The performance indicator ( vacuum gauge ) is nearly see through or hollow so it is the best option for lighting.
Worst options from lighting stand point is tach or clock. These are solid bodied like the blank but... their flat dark color absorbs a lot of the light that hits them.
Gotta tach ? Wrap white tape around it and marvel at the difference, with any bulb type.
