You are correct, however, the wiring has more available amps/voltge to fire those lights with the headlight removed from the bulkhead/welded splice. That's why the instrument panel and marker light get brighter.
LOL. Well "technically" correct but if this is the case, then the light kit was not the "cure" only a "change in symptoms". In that case the usual MAD article and bad bulkhead / ammeter connections need fixed
I give ya kudos on your headlight / relay kits those are a good setup.
