I bought it for Regius Ace which I delivered in April. Since the connector part has the same shape, there was no problem but the lamp itself does not enter slightly big! It is not even a level like pushing in by forcibly! After all, it was just garbage. "Is it possible to replace when a genuine high mount is attached?" What does that mean? Hiace and Regius Ace are the difference of dealers and I think that it is the same. I want to return ~!
