Can I install the new AUDI A4 lights to the older 2007 AUDI A4 series?

And how much does the installation costs?Can I install the new AUDI A4 lights to the older 2007 AUDI A4 series?Cant do it. The lights wont fit. I hear that there are aftermarket parts that you can install to make them look similar though. Do some research on the net and find the ones you like best.
