First off a few FAQ's
Why Use Load Resistor In The First Place, The Advert For My LED Bulb Says I Don't Have To Modify Anything
This is true for the majority of old cars, however most new, and the Grande Punto can detect when there a bulb has blown, it does this by measuring the "load" in the circuit, when you replace the filament bulb with an LED, the LED does not draw enough power for the body computer to recognise as a full "load", therefore it turns off that circuit until a "load" is present, so your LED doesn't light up. The Load Resistor fixes this problem by drawing power and tricking the body computer into reading a load in the circuit and therefore keeping the circuit turned on.
What is a load resistor?
A load resistor is simply a resistor inside a heatsink to stop it from overheating while in continuous use.
