For all those needing to replace dash (Tacho) board lights. Speedo lights.
Tools required are
Phillips head screw driver.
Bulb (9001006038) - Orange type. T10 bulb with a orange sheafing.
There are 5 screws holding the plastic dash board down.
2 right at the bottom, 1 in the middle, 2 where the taco is.
3 screws holding down the taco down. 1 on the top, 2 underneath the taco.

Back of the board.

to replace just twist the black backing of the bulbs and they pop right out.
Faulty bulbs

when replacing i tried using just the normal T10 wedge bulbs
you can see a slight difference from 0km - 120km as seen in the pic.

fixed and all back to normal.

Hope that helps.
Simon.
