Your headlight switch has a lot of terminals for each of the different lights it controls.
One of those terminals is for the headlights, and a separate one for the dash lights and tail lights.
That is because the headlights take more electricity, they need a separated circuit.
You could have a bad headlight light switch, a loose plug that goes from the inside of the dashboard through the firewall into the engine compartment, or perhaps a bad fuse or circuit breaker in the black plastic box under the hood of the car for the headlights.
You might also have a broken wire due to a previous car wreck's damage.
You could have a defective./rusty/corroded ground wire, too.
Someone will need to chase all these possibilities out.
God bless your efforts.
The new headlights, probably blew the fuse check the fuse and relay if so get a bigger fuse to run the new headlights. Remember when replacing any light in your vehicle to not touch the glass part of the bulb with your bare fingers..
These are all different circuits. The brake lights are on a 10amp fuse - the headlights are on a 50amp fuse - and the parking and dash lights are on a 20amp fuse. Do you have power going into the headlight switch and the brake light switch ?
