Late Minis (1986-on) used a larger plastic lens on the front panel turn indicator lamps. These are amber as found in many sales markets, but were also available in clear, often called "white". Retained by screws, unlike earlier "bee hive" lens that was held in by a chrome ring. Sold each.
See CDU3374W for clear/white lens.
