How to install led?

The generator generates AC power, so the LEDs of 2 colors should be installed in reverse.Because the LEDs of different colors have different starting voltages, if the installation direction is the same, only red will be bright, because red requires the lowest voltage, so yellow should be opposite to the red mounting direction.
Led long foot is positive, short foot is negative
