Nemasys
They will not fit straight out of the box.
You have 2 bulb sockets for the stock tail lights that you need to put into the altezza. Once you take out the original lights, you will notice one of the 2 sockets is noticably bigger then the other one (its longer).
The way they made the socket holes in the altezza, the original bulb sockets will fit without a problem but once you put the tail light back in place the longer of the 2 sockets will hit the body of the car, preventing the altezza to fully go in place.
