Aux light upgrade, use same harness?

I have PIAA mini halogen driving lights on my truck and I want to know if I can swap out these 2 lights (either 35w or 55w each) for 4 18w LED pod lights, using the same PIAA harness. I know this is a high quality harness used in different PIAA kits. I would probably use butte connectors to split each side's light wire.

I would think the harness would be fine. The two LEDs pulling 18w each would be pretty much the same as one of the halogens if it was only a 35w, and if they're 55w, you have more than enough room to upgrade to those LEDs.
