Some care some don't. I got pulled over with the new boat and was told my letters had to go. They were black and grey on a black boat . Not my doing they came with the boat. No ticket no big deal guy just said get them changed. I said okay! I can't stand the boring Walmart letters so i called up Daryl at Iguana graphics. He can make you a custom set of anything you want. Best part, he told me if LEO doesn't think they will work he'll replace them for free. So what do you have to loose?
