To me, it looks great already. Opinion: I think it would look much cleaner if you could use a more modern traffic light image there, an image of a traffic light with LED lights. If you wish, I can go out and take photos of those.
Best regards









Regarding the virtual start lights, I don't think they're really important, and can't believe people really think it's a significant issue that they've changed slightly. You only see them once per race for a few seconds (unlike the actual start lights, which you see every lap when you go past the start line) and as long as they're clear and do the job, then it's job done imho.
