If you have lost the ground on a dual filiment lamp or sealed beam,
you get three filiments in series. That is each filiment sees about
four volts instead of twelve volts and is therefore very dim. Start by
turning the lights on on low beam and looking if both filiments are
glowing. If two filiments are glowing then you have to reestablish the
ground path, to do this, you determine which if the three tabs is the
ground and install a new wire from that tab to the body.The third
filiment is one of the two filiments in the other headlight.

On high beam both filiments in one lamp see no voltage.
