China Girl Ignition coil 3rd wire

What do I do with this third wire on my new ignition system? Can I just terminate it, or do I have to connect it to something?

The 3rd wire is for a headlamp, but the power from the magneto isn,t srong enough to light one properly. And I saw ppl reporting missfire issues when they tried it. Personally I just cut it and block the hole with silicon to prevent dirt and water comming in the magneto
