I guess it's my age 81, but fought rather than fit or fighted as past tense for fight seems right to me. However, lit rather than lighted as past tense for light seems right to me. I guess to be consistent Joshua should have fit the battle of Jericho as the song says. I certainly do not go along with lighted or fighted although I have never heard fighted. Of course, I am a fan of fled over fleeded and pled over pleaded although my spell checker is not.
