Tacho lighting???

Naaabbbeannndd…. I recently bought 4 super bright blue LEDs with glass socket mount for the speedometer lighting. Does also super only work unfortunately the light is still too dark and uneven, apart from that the red areas and the 50km/h line garnet shine… Sooo…and I recently read somewhere that the Omega A was to be obtained with both white and green speedometer lighting. Is that true? If yes…one knows why the lighting is grürü Is there a green foil on the back of the tacho disc? So it was then with my Sierra… Then I would look that I get blue foil and then glue it from the back onto the tacho disc and cut out the red areas. To do this I replace the 2W glass base lamps with 5W pears for the lighting. One other idea? Would be grateful for tips.. MFG Alex
