Headlights and hazard blinkers problem

I have a 68 Dart. I just replaced all the fuses in the fuse block and every light bulb in the car. When I turn on the headlights, all the parking lamps light up fine, but the headlights do not. Also, my blinkers work perfectly, but when I brake, they stop blinking. Also, my hazards do not blink unless I honk the horn, then they start blinking. Any help would be appreciated. Thanks, John...
