spot lights

hey every one trying to find out wot sort of relay i need to hook up 100w spot lights

30 - 40 amp relay will be fine as your only going to be pulling low amps

I'd go 30 amp relay, have a look here too

100W spotlights draw 8.33A each.
A total of 16.66A will pass through the power and earth side of the circuit and relay.
A 30A relay with one main input and 2 outputs would suffice.
Ensure you fuse the supply to the load and switch circuit using 20A-25A fuse.
If you are fitting driving lights, the power for the switch is to come from the high beam circuit, if fog lights, from the park light circuit.
Or just free-lance it
Ensure your wire is capable of carrying 20A to each light and to wherever you earth each one.
Ensure that if your relay has one input, you either run 2 x 20A wires, or wire suitable to carry 35A.
The switch side, of the circuit will only draw bugger-all.

And a quality 30 amp, not a supercheap $2 relay

thanks guys

Isn't it illegal to have fog lights on all the time theyre only permitted when there's fog.. I wouldn't be going off the park lights unless you put a switch on also

This would be correct, I went through a RBT bus and the coppers asked me to turn them off or he will fine me. "As fog lights can only be used in adverse conditions where appropriate. "
Quoted by the officer.

I believe all driving lights must have their own switch. Even if they are triggered by the high beam.

That is true, on their own switch triggered by high beam is the only legal way to have them.
