If you are 100% sure that the wiring is perfect, per the diagram...get ahold of Hyperlites.
I know you are going to say "I've already tried and no one will...". Just realize that it is a small business. Some small business owners have real jobs, some don't. Some small businesses completely shut down due to vacations in the summer time (because it is only a couple people). Drop them an e-mail, tell them you can't get ahold of them by phone and are having a problem.
I have 2 bikes with the dual function lights. One bike had an issue, and over the phone they decided that it was defective. They sent me a new controller...and asked "when you get it all fixed up, and have time, send us the defective one to look at". Very nice and accommodating people to work with.
