Driving lights questions on wiring

So I'm looking to wire up these lights on my 3rd Gen (I'm aware they are cheap lights) and from what I'm reading online I should use a relay in the wiring of them. The cheapo kit they include is just a fuse some wires and little switch. So if these lights are 55w can I buy another better wiring kit with a nicer switch like this and a relay?I don't see many kits with that low of watts, they are most like 255w. Im completely new at this so any help would be appreciated. Im also not opposed to buying a whole new set up with lights and a wiring kit if that makes more sense too.

 

I guess my question is if I buy a higher watt wiring kit and the lights are pulling less power than the kit is rated for it should be fine? Only if I was attaching lights which were higher watt than the kit would heat become an issue.
