Your link does not point to a specific bulb so cannot say whether or not they would fit. I bought some that were too long - there is not room for much extra length, approximately an extra 10mm over the standard W5W length. Standard W5W is 27mm long x 10mm diameter, The over-long bulbs I bought had a diameter of 11.8mm and went through the aperture OK.Which sidelights do we buy now? The link has expired from Dantolo's original post.
There's so many LED SMD and they all look different.
These say they are BMW/Audi only, but would they be the right shape and size for GTV?
These look like they will fit W5W LED and reviews are good.
