There was a service bulletin I read from GM about the 'doubled' lights in the windscreen, although it was directed towards the HUD image on Chevy trucks and Corvettes being doubled. The HUD windscreens have a special polarized film applied - the double reflection is caused by the light reflecting off the inside and outside surfaces of the glass, and the film is supposed to counteract this.

The bulletin asserted that some HUD cars had left the factory with non-HUD windscreens fitted, I would get it to the dealer and show a tech exactly what you are talking about.

The only HUD 9-5 I drove was during the day, so I can't say I noticed it myself.

Definitely bring it up at the dealer though, it shouldn't be doing that.
