No Headlights on my 150ZK Xingyue trike!

[savy09]

No headlights, flashers work as well as directionals and rear lights. Checked all connectors they are ok.
OR:Could it be the headlight switch?

Removed the regulator/resistor and found white corrosion,only 2 of 6 bare wires connected to the regulator bottom of which has white corrosion and other 4 wires corroded off regulator (green) maybe from water damage? Will a new regulator solve this headlight problem?
Scrappy is trying to find one.
