4 pin relays for headlights

I am looking at bosch 20/30A five pin relays now, and if i do this as 4 seperate relays, that box i found on evilbay should be about perfect. What are you using size wise for blade fuses? I just bought a pair of GE H6024NH halogen sealed beams. I assume 50w/65w

The headlights are direct off the battery through the relays and not fused but the rest of the car is on the self resetting breakers.
I ran the 10 ga wire for headlight power through vacuum tubing for insulation insurance for it's route along the underside of the lip on the radiator support where the OE metal tabs for the old wires are.
I used a 30 amp breaker for the main cabin power instead of a fusable link.

My electric cooling is also direct off the battery through a 20 amp inline blade fuse using a relay that the thermostat for the fan controls, so there isn't much load on the thermostat switch.
Everything inside the car is pretty much original glass fuses and the factory fuse box, and almost everything in the way of lighting except for my headlights are LED so there is very little load anywhere.
My wipers, heater blower, headlights nor signals slow or dim at idle.
