Usually this is due to the wire going to the neutral switch being pinched against the frame somewhere, and shorted out. If you ground that wire, it will cause the neutral light to come on.

It can also be caused by excessive carbon build up in the switch itself.

here is an excellent explanation on how it works

and here is how to remove and replace it, in my opinion it is better to buy a new one and replace it. after you are satisfied your switch is faulty.
please dont try to clean it by diluting the oil with marvel oil, AtF , or any other supposed cleaning agent. change the oil and filter regularly and all should be good.

Earlier bikes used diodes that go bad and cause this issue, but they went away in 1978 so diodes are not involved in your 1979 neutral light issue.

while i am fairly certain the cause of your problem is not the diode, it must be pointed out your bike does indeed have a neutral diode. its purpose is to provide a ground via the clutch switch to the start circuit, when the bike is in gear.
some diagrams refer to diodes as silicon rectifiers, but they are a diode. here is the wiring diagram for your bike.

and here is another diagram showing the diodes place in the scheme of things.
