I have a 540i also. Bought the Angel eye Headlights off of ebay from Pavrac. They were a good deal and just like OEM 2001+ (the year they were introduced). Had to slightly bend the a/c fill line to make them fit but they fit without a problem otherwise. Be careful when you try to bend the a/c line. It is aluminum.
Pavrac also sells celis look a like tail lights, clear/red. These mods make your 97 look just like a 2001+ (except for the black side & bumper moldings). I am looking to replace my side and bumper modings with color matched trim. Going to use the side moldings, paintable, from the 2001+. A slight mod is needed to accomplish this but they will fit. Once that's done it will look just like a 2001+.
Try Pavac's ebay store...........
