I changed the amber side turn signals on my 2004 Z4 today. I chose to order the clear assembly and try to remove the roundel from the ambers and use it on the clears. The whole process was pretty easy - less than an hour for both lights.

This method is much cheaper than purchasing an entire assembly ($70 each on some sites). I ordered the two clear light assemblies from JD at Crown BMW for $14.17 each plus shipping. The only other expense is a roll of 3M Super Strength Molding Tape (1/2" wide, Part 03614) for about $10 and some Goof Off to remove the old adhesive.
