I put Clear Alternative lenses on my front and rear signals. Great look and fit by the way..They come with new amber bulbs. I want to go to LED bulbs to be as bright as possible. What I am wondering is the rear bulbs are turn signals only, single filament. The fronts are running lights and turn signals, double filament. Can a LED light do double duty so to speak? Autozone has the bulbs with the correct connection but there is no such thing as a double filament LED. Anyone run into this yet?
