I've just replaced my heater control bulbs with the Volvo original parts at the stupid price. In the past I've tried LEDs, which were too bright and not the right colour. Until I found this thread I've never seen any suggestion that the blue caps might be available, which has put me off replacing the bulbs in the holders. Did you manage to source the blue caps at a sensible price?
I've just ordered some 3mm diameter bulbs (from Ebay) which I believe are the right size for the hazard warning switch. I assume for that application there is no need for a blue cap as it illuminates the red triangle.
I'm now contemplating the illumination of the info centre knob. It's still working but it's gone yellow, which looks daft with the new (blue capped) heater control bulbs. So I'm heading for the blue cap problem again, but for the info centre knob. Are the bulbs the same as for the hazard warning switch (3mm diameter) and, if so, did you ever find blue caps that would fit those?
