Sounds like the system is good. Have you checked the wiring to the bulb, or the grounding of the inst panel? Also check the resistance of the plugs, even though they are new. Carbon can create a bridge. The light will not come on if two or more plugs are bad.

Since it starts well, I think your GP's and relay are good, but it never hurts to recheck everything.
