The lightbulbs behind the heater controls are bulb and socket as one unit. Generally they will cost you £ 8.00 + per. (there's another one for the ashtray)...
I have made a simple conversion so that these can be used in conjunction with the little glass bulbs which simply push in...
Takes about 30 mins and some fiddly work, but if you're handy, have a soldering iron, some thin copper wire and a .5mm drill bit, you can do this...
The push in bulbs go for around 10p - 15p...so huge saving!!
