The controls for the heated seats in my SAAB each contain two tiny
bulbs. They appear to be filament rather than solid state and have a
coloured silcone cover. Each bulb is mounted on a removable carrier.
I've put a couple of very poor (sorry macro photography is not my
forte) pictures he http://richard2808.fotopic.net/c1050691.html

Suggestions as to source of replacements would be much appreciated. New
switches are prohibitively expensive.
They look very similar to the ones used on Saab dashboards, should be
worth going to your dealer and asking them. The wattage is usually coded
by the colour of the plastic bit so they should be able to work out what
they are easily. You can buy LEDs with a built in series resistor for 12
volts if you want to have a go at replacing them but you need to make
sure the viewing angle is wide enough for your application and it'll be
fiddly.

TIA
