Part number for Dash bulbs on a 56 plate ford ka?

[Futureclassic]

Hi guys,

Just bought mrs Futureclassic a 56 plate Ford Ka, all seems to be okay with it, but the instrument light doesn't come on when you turn the lights on.

Can anyone tell me what the part number for replacement instrument light bulbs and a place to buy them. Is it easy enough to replace them? Also does anyone know of any other reason that these lights may not be coming on? The fuses are all fine by the way

Many thanks

Just go into any spares shop and ask for a couple of 501 bulbs,thats all they are.
