I am looking to buy a couple of relays to wire up some driving lights and I'll also be fitting a headlight kit which will also require some additional power.

The Narva catelogue shows three different types of relay, ie Resistor, Diode and and one with neither. It appears the resistor and diode are across the trigger terminal and earth.

I have concluded that the diode type is not required for my purposes??? but I cannot understand the purpose of the resistor. Is it to protect the coil when the relay is engaged for long periods??

Will I be right in using the type that has neither the resister or the diode?? The relays are at: http://www.narva.com.au/Switches_18.html

Thanks in anticipation!!
