When we installed some new storage under the stairs recently the clear-out unearthed a pair of E39 rear light clusters, pre-LCI ambers. I vaguely recall that someone who did a clear upgrade gave them to me when I had my first 523i many years ago.
They're free to a good home if they are of use to someone. I know that most people prefer clears, even on the earlier cars, but they look to be perfect, so hopefully someone can use them rather than binning them.
