Youll need 3xT6.5's and 3xT5's, These can be bought from ebay, for as little as £10 for the lot.
First remove the Dials, there are 4 screws holding the cover one, 2 under the dails either side of the steering wheel, and 2 behind some clips behind the cover, youll need a stubby screw driver to remove these, as they are pain! once loose, unplug the Hazard switch and other buttons, There are then another 4 screws.

Once removed, unplug the speedo cable, and the 2 other plugs that are connected to the dials.
Once removed, locate the bulbs that need to be changed

T6.5 3xLED

T5 LED

Next bit is the bit that took the longest! the bulbs need to be in an exact way other wise they wont work! the way i did this, i plugged the dials back into the car with the 2 plugs (dont plug the speedo in) and get a cover of some sort (Jumper will do) one by one, take a bulb, put it into place, turn the sidelights on, then cover the dials to see if its lit up, if not, take it out, and turn the holder 180 degrees and re-try, if it doesnt work again, remove the holder, take out the bulb and rotate it 180 degrees in the holder, then re-try the holder and light again.
ill be honest and say i ordered the wrong bulbs, as the T6.5 should be T10 (or sidelight bulbs) but they dont come in the 3LED layout and can cause hotspots (Spots on the dials appear better lit that others)
I used T6.5 instead of T10, and have no issues.
After all the bulbs are working, re-assemble the dash.
and enjoy!
