I got my red/clears about 2 months ago and just useing the stock white bulb in the turn signal. I haven't had any problems at all in NJ. I also kept the stock bulb in my front clear signal. Since I have hyperwhites, the stock looks kinda like an old amber so its ok so far. I really wouldn't worry about your rear turn signals. If you don't want to use orange, how about yellow? That would be legal too.
