Thanks Uberwagon, yet the link is barely useful
it gives just the Sylvania code for each bulb, not the actual wattage and other specs of the bulb. Here there are no Sylvania dealers, so we have to do with Osram, Bosch or Narva...
On the other side, the small weirdo 0.4-1.2W dashboard bulbs can be easily replaced with a type of small bulb used for electronic appliances... so I don't have to pay the price of MB stealerships
the real problem is to pull the damn gizmos out of the dash; still not figured how to replace those in dash vent adjusting wheels, or in mirror-adjusting button
