I'm putting a set of Narva Ultima 100w driving lights I had lying in the shed on the EA. I bought a 30amp, 5 pin relay for them from a shop in town and and according to the Narva website it has a resistor in it
. The standard relay that comes with the kits is a 30 amp, 5 pin mini relay without any resistor or diode. I didn't give it much thought till now.
My question is: Does it matter about the resistor or should I get one without?
What is the resistor for?
I hope someone can help
