Hi, all the bulbs are 1.2Watt capless
Does you car have air-con or not?
air-con bulbs cost €15 each form alfa, non air-con cost €1
non- air-con bulbs can be replaced by removing the radio this give you access to the back of the switches. Now pop off the adjuster/s & then the front cover/s, watching for 2 little springs. using a long nosed pliers the bulbs can be turned thro 90 deg's & caught at the back via the radio slot. Fitting is a bit tricky but basically the reverse of removal.
air-con: you need to remove the radio, ash tray & central console. the white controller module is held in place by 4 screws. easy enough to remove. be warned if you drop or hit this unit too much the 'good' bulbs will blow so be prepared to replace all 3, in the past I've soldered in 1.2w bulbs onto the circuit board, much cheaper fix.
