The resistor in parallel with the light lowers the resistance of the field
circuit to provide the initial charging current to get the regulator cutout
relay to pull in. Of course the solid state regulators do not have a relay
anymore but the idea is the same. 16 ohms will not be a problem. You
probably will not even notice the difference. Without the resistor you
typically have to rev the engine to get enough current going to start
charging and cause the light to turn off.
