I'm a bit confused. You say that you have yellow indicators in the front and red in the rear. Is this common across the US? Most of the rest of the world use amber (yellow/orange) indicators, both front and rear . Red is only used for rear (tail) and brake lights and passive rear reflectors.
No, the US requires amber signals. The center tail light is red on my led unit, but the signals are amber. Up front I have clear lenses with amber bulbs.
