The FXR Fused E-Shield Power Supply Cable is a replacement power cord designed to connect compatible heated electric helmet shields to a snowmobile 12V electrical system. It supplies power to the shield heating element to help reduce fog and frost buildup during cold-weather riding. An integrated fuse adds electrical protection against overloads and short circuits between the vehicle power source and helmet connection, making it a practical replacement or spare for compatible FXR e-shield setups.
