Replaced blown illumination bulbs in my dashboard last night.. one of those jobs that "I was getting around to.."
Bit fiddly.. to get dash out but all in about 1/2 hour start to finish. Bulbs are from Hellfrauds "HB501" 12v 5W - £2.69 for 2, theres 4 total in the dash (BTW

same bulb as sidelights).
Look like this....
http://www.thetoolboxshop.com/ab501-t10-12v-5w-501-capless-automotive-bulb-749-p.aspEbay has squillions for sale, search for "501 bulb" - a lot cheaper, also there are LED ones availiable if you want funky colours (not legal for sidelights - interior only)
Connectors for illumination are the white ones, turn anticlockwise 90 degrees to release, nice easy job if SWMBO is watching "Her Soaps" and Eastendercorryfarm isnt your thing.
