You can get tint films for the headlights - there’s a mob in the States that do them - but check MOT requirements first, coz it may be hideously illegal. In Oz, such a mod is a guaranteed default notice, which Dumb Julian (my Trump name) discovered AFTER ordering the films!... when Trups had the headlights out, I snapped this one. Think it looks brutal with black headlights. If only they were a thing.
