If the bulb holder doesn't fit the lens, (i.e it's too small), then they were probably copied from the Nismo clear repeaters for the March. They don't share the same design as the UK Micra, which is just the sort of mistake I would expect a cheap copy to have.
We robbed a set of bulb holders off a March in the scrappy to fit the clear Nismo side repeaters when we first got a set.
