This will fix any problems you have with dim headlights. On most older foreign cars, the wires powering the headlights are too small to do the job. Add to that the voltage drop that happens when the wires go from the battery to the switch and back to the lights and corroding ground connections.

What this circuit does is use your existing headlight wiring to trigger relays that run power to the headlights directly from the battery using thicker wires, rather than powering the lights with thin wires that go from the battery to the dash and back to the lights.

You can get the relays at any parts store for about $6 each... they usually
sell them near the fog lights.
