It seems I was spotted. Flinders Lane Melbourne yesterday around 3.40pm. A guy runs up to the side of the car and say "where'd you get those lights, I've got a CC", time was short so I gave the website address for us and said I was a moderator. He said "Are you Frosty" - no joke! He gave his name but I missed it as I was driving off. If you read this I must apologise that I couldn't stay to chat. If you want the light they're available from AutoParis in Box Hill - they're in the phone book, ask for Paul.
Not sure if it's world famous, but goodness the internet is a powerful communicator. Still chuckle when I think of it. I almost fell out of the car with shock.
