Hello

its likely that the ground / earth wire for the headlamps is corroded so there's excess current being pulled through the headlamp

if you check the chassis rail behind the headlamps there should be a large ring terminal thats bolted to the metal - undo this and wire brush the ring terminal clean

do the same for the bolt point and if necessary replace the bolt with a new uncorroded item
