I don't believe so. From looking at the manual, they will only work on the front. Obviously these ones are yellow, but even if you wanted yellow in the rear, they are PY sockets on the front and the manual indicates the rear sockets are normal P sockets. So, instead of PY21W (front) you'd need P21W lamps for the rear.
