It's a new design trend I guess. I know how you feel, it gets annoying. Orange turn signals are so much easier to tell from red ones. However, it's not that bad with Japanese cars because they usually separate the turn signals from the brake signals. In some American cars, the turn signal lights are actually the same as the brake signal lights!

How's that for confusion?

There's really nothing you can do about it, unless you talk to the styling departments of every major car maker, or they change the safety regulations.
