take the bulb out and messure it. It could range. I did the same for my Scirocco and ordered the wrong one so I messured it (in mm) and got the right size from here

  I want to try replacing some of my dome light bulbs with LED festoon bulbs,
but I'm having a hard time figuring out what bulbs are in there now.

The Sylvania web site gives two bulb numbers for the Vanagon dome light,
6411 and 6418, but it seems to me there's only one size/type of bulb in
them. Which bulb number is the one, and is the map light the same bulb?
