Load resistors do not differ from the normal resistors but they are used at the output of the circuit. The main reason of applying these load is to increase or decrease the power at the load according the requirements(i.e to make remain constant power in the circuit).
LED turn signal bulbs without Load resistors, you will experience the notorious hyper flash issue. Hyper flash is exactly what it sounds like, where the turn signal light flashes rapidly. Not only is this ugly, but you may also attract the police who think your bulb is burned out. This sounds completely unnecessary and a huge hassle to boot.
You will need 50W 6/4 OHM load resistor and tap the load resistor to the stock harness in parallel. Load resistors also have no negative or positive, making it easier for you because you wouldn’t have to worry about which wires goes to which side.
Load Resistors get really HOT when working. Mount it on metal surface, NOT plastic. Load resistors can work on any vehicle and can be connected across the turn signal bulbs or License Plate Lights to simulate the load of a regular filament bulb (2 Amp load).
