Motorcycle Repair: Making trunk lights on Ultra run-turn-brake, filament bulb, lighting companies

Question
How do you rewire the trunk lights on a ultra to be run-turn-brake.  I saw one last week on the interstate.  But after asking three Harley dealships, none could tell me how to do it.  Can you help?

Answer
That is somthing that is added on, probably aftermarket. In order the make a light a run and brake you would have to have a two filament bulb. Check with some of the aftermarket lighting companies online and you might find what you are looking for
Good luck and happy riding
