I would also suspect a wiring fault, like the earth connection is corroded.
Assuming that you have the lights full on, then it will not be the dim-dip
resistor, as that is not in circuit.
Also, is it the same on dip and main beam? Assuming both are dim, then you
can be sure it is the earth, as that is the only common feature.
