They were made by a company called Mistral. Unfortunately, they're out of production now. I'd love a rake of my own, but I wouldn't be respraying them, that's for sure!
What Sean is saying is that he had all the lights on at the same time because he felt like it. He's already said there's nothing wrong with the decoder.

Give Templot a try... takes a while to get used to but it's great once you get used to it. It has plenty of features, too, plus it's free to download.
