REPLACE FOG SWITCH BULBS WITH LEDs:
When your fog lamp switch bulbs burn out, it is not that much more difficult to replace the bulbs with LEDs and resistors.  You will need to solder one 690-Ohm resistor in series with each LED, and then solder the leads to the pins in the switch.  Pin “1” is the (+) side of the illumination LED.  The (-) side of BOTH LEDs will be soldered to pin “2”.  Pin “3” is the (+) side of the indicator LED.  This modification also satisfies the condition where the indicator lamp is out of synch with the fog lamps if you have done the fog lamps + high beams modification.
