Hey. Does anybody know what bulbs are needed for the interior of a w164? For vanity, Lower door and foot wells are they are festoon 39mm?

If I change for LED do I need canbus for interior or are they not on the error system?

Thanks.

 

I think 39mm was most of them. I changed out all my interior bulbs with white led's a few months ago. They do not set off the bulb out system, so you do not need Canbus bulbs. I bought most of mine off Amazon after cross referencing on the Slyvania Auto bulb search site.

 

The 2 main bulbs in the front over head console were the toughest to change and u have to buy the very low profile bulbs (of the T10 type I think).

 

I have changed all the interior bulbs i will post with pics and maybe video to show how its done and what bulbs to use
