Dont look like they will fit in a standard bulb holder ? Have you got to change anything apart from the bulb?
The wedge type are whats fitted to my 2cv and no they wont fit a the more normal type holder,check which you have. There is no other change needed just replace the bulb or in this case just replace the bulb holder to take these, but I have also used the normal fitting with an LED replacement.

Well worth doing as the bright white light makes your speedo very clear,
Here is a link to replacement bulb
