Haha...maybe a good match to go with your new gauge warning light metal strip.
A fellow board member here helped me find them. They are only sold here (as far as I know)..... Not cheap for sure, but I really like the look in the car, as it gives it a more expensive look to the gauges when there's already so much plastic in the car...
