Taking the stress off a weak switch is the right place to use a relay. But you may have to shop a bit to find 6 volt relays.

I suspect the new switches are being made to 12-volt specs instead of 6-volt.

If you can't find 6-volt relays another alternative that might solve the problem without relays would be to convert to 12-volts.

Its too much current (amps) that I suspect is causing the problem, and converting to 12-volts would roughly cut the current required by the headlights in half.

Of course running 12-volts you might be tempted by high power lights, and then you'd need the relay solution again...

It's true. I really don't do anything but browse the Internet looking for trouble...
