hevac bulbs

hi people just a quickie, im finally getting round to doing my hevac bulbs(another blew yesterday!). Can anyone point me in the right direction to which ones to get? Also my cruise control switch has given up lighting up, are they just a replacement bulb or is it a sealed unit and i need a whole new switch? Thanks.

All you need to do the job,
LCD Backlight Repair

In the cc switch, just need to replace the bulb (actually there are two of them...)

thanks for that have been trying to find the part number for the bulbs for a while now! theres a guy on ebay selling a hevac bulb kit but thought it was a bit pricey.
