How do you hook up an after-market headlight on ktm 520?

To hook up an aftermarket headlight on a KTM 520, first, ensure you have the necessary wiring harness and connectors compatible with your headlight. Disconnect the battery, then remove the stock headlight assembly. Connect the new headlight's wires to the motorcycle's wiring harness, typically matching the positive (usually red or yellow) and negative (usually black) wires. Finally, secure the new headlight in place, reconnect the battery, and test the light to ensure proper functionality.
