Today I pulled the bulbs from the climate control unit on my benz.

The old bulbs have the following written on them: OS 12 / 1.2

I did a quick search on ebay and found the following :

10x 1,2W 12V W2X4,6d T5 OSRAM 2721 ring panel wedge auto car bulb w2x4.6d 1.2W | eBay


the numbers seem to be the same, 12v, and 1.2watts, but i am not sure about the base , which is W2x4, 6d. will these bulbs fit in the climate control bulb sockets?




question #2:

i also need to replace a bulb in the instrument cluster, the one for the tachometer. will i be able to use this ebay bulb, or are the bulbs in the instrument cluster different?

thanks in advance
