You describe an intermittant problem.
Could be the switch, the wiring, the bulb holder or the connections.
Intermittant = Hardest to diagnose correctly.
Need to do some further troubleshooting.
Trouble shoot the switch check continuity both open and closed.
Look at the wiring for obvious signs of wear.
Check the bulb and bulb holder for corrosion.
Unplug all pertinent connections, check for corrosion and apply silicone grease to help weather proof.
One area you may want to look at closely is near the top triple clamp, you'll have to remove the trim around the ignition and the plastic cover over the top triple clamp, both just pull off. The wires are held in place (out of the way of pinching) by a zip tie affair, make sure the wire looms are indeed secure or the neutral light will be only your first problem.
I'll try and get a picture of what I'm talking about when I get home this evening...before the margaritas.
