You can make do with one if you have a relay harness that's only using one relay for both lights. Darketernal3
explained the method best.

1) If you have independent relays, where each headlamp signal controls a separate headlight then yes, you'll need an individual resistor for each headlight. The relay I had uses the driver's side lamp signal to activate and the passenger side was left plugged into the resistor and grounded. Both lights would be switched on regardless if the passenger side had a resistor or not.
2) If you did not put a resistor on the passenger side, or the resistor occasionally didn't impede the current; like mine before I redid it. You will get a bulb dip error. The lights will still turn on, but the bulb dip will come on every time you turned on your lights. If that doesn't bug you, you can go without the passenger resistor.
Edit: I bought my relay from retro-solutions, the original link provided.
So you would only use the resistor on the passenger side, connected like in the retro-solutions diagram. The relay harness on the driver's side that would connect to the resistor in the diagram instead connects to the factory bulb harness. The rest of the connections are pretty straight forward from there.
Make sense? I'm personally running individual relays for each headlight so mine is setup exactly like in the diagram. It seems like this method has worked for a few people, but I have not tried it.
