1934 Fordor headlight problem

[Feathercraft56]

I have a stock 1934 Fordor and when I apply the brake, the headlights turn off and when I disengage the brake they turn back on.
I replaced the factory headlight/horn/tail light harness and all factory female connectors as well. At the exact same time when the brake light switch engages the tail lights the headlights turn off and automatically come back on when brake light switch is disengaged.
Any help would be appreciated very much.
