Do I need relays with these headlight choices.

Will they work better than an old style bulb, yes.

Will they work to best performance using the factory wiring, no.

Even the OEM headlights work much better when fired by a relay kit. The OEM harness has way too much voltage drop across the run to power the headlights properly.

Kinda what I was going to say, as a matter of fact if you put the relay kit in first you might decide you don't need new lights at all.
I didn't need new lights, and was really surprised at how much farther down the road I could see with the ones I had.

In my opinion relays are just as much of a must as frame connectors and the ammeter bypass.
