I'm looking at a diagram and wondering if I could use just one resistor to limit the current of the LEDs instead of multiple resistors so that the cathodes are all connected to the same resistor.   Model Traffic Signal

What's the difference of placing multiple resistors and one resistor for limiting the current of LEDs?
