92 Suzuki Swift Headlight problem

Hi Everyone. Please help. Just bought this car and headlights quit working. Have checked the fuses...all OK. Dash lights, signal lights work OK, so what can I check or look for. Thanks for any input you can give.

Check your grond wire from the back of the headlights, mine did the same thing and i just replaced the ground wires, prob solved.

The headlights work on a grounding type system.
The headlight switch runs to a relay and the
relay runs to the under dash fuse box.
The relay grounds the brown/yellow wire
and it runs to the white/black wire which grounds
the headlights through the dimmer switch.
Make sure the two wires are not bad in the fuse
box. They may have burnt or may have a loose
connector. Ground the white/black just to
test if headlight switch is working,
The headlights should work with it grounded.
