The FZ-S Version 3 bike typically comes with a stock headlight that meets the necessary specifications for optimal performance and safety. While it is possible to install an extra light or upgrade the existing headlight, it is essential to ensure that any modifications are legal, safe, and do not exceed the electrical capacity of the bike's system.
Using a 72-watt extra light would require checking the electrical capacity of the FZ-S Version 3 and ensuring that the bike's electrical system can handle the additional load. It is recommended to consult the owner's manual of the bike or seek advice from a qualified mechanic or the manufacturer to determine if such modifications are suitable for your specific model. Additionally, it is crucial to comply with local laws and regulations regarding vehicle modifications, including headlight upgrades.
