Why Do You Need Load Resistors For Switchback LED Bulbs

The switchback LED bulb needs 50W 6-Ohm load resistor to ensure its proper dual-color alternating function. You must tap this 50W 6-Ohm resistor (not the 25W resistor) between the ground wire and the turn signal light positive to ensure the switchback LED bulb flash properly meaning when headlight is off, the switchback LED bulb flash amber-off-amber-off and when the headlight is on, the switchback LED bulb lights up and stays xenon white, and when doing turn signal, the LED bulb blinks amber-off-amber-off and returns back to white when the turn signal finishes.
