Why you need this controller Durable, weatherresistant housing and reliable electrical protection reduce failures and downtime on 12V vehicles. Compact handlebarmount design puts multiple controls within easy reach, improving safety and convenience while riding. Designed specifically for 12V motorcycle/ATV/scooter electrical systems to avoid compatibility and wiring issues. Key features and benefits Material and finish: Precisionmachined aluminumalloy shell with anode blasting process finish for corrosion resistance and longlasting appearance. Compatibility: Fits motorcycles, ATVs, motorbikes, and scooters that use a 12V battery installation. Mounting size: Mounting holder designed for grip diameters 22–23 mm (0.78'–0.90'), suitable for standard handlebars. Controls: Userfriendly assembly with multiple buttons and switches for convenient control of auxiliary functions from the handlebar. Electrical protection: Builtin output circuit protection, overload protection, and reverse polarity protection. Multiple protections reduce the risk of damage to the controller and vehicle electrical system. Indicator: Product does not include a pilot lamp; plan external indication if required. Performance and reliability Robust aluminum alloy body and anodicstyle finish resist wear from vibration, weather, and handling. Multiple electrical protections provide safer operation during installation and in service, protecting both the controller and connected accessories. Practical applications Motorcycle auxiliary lighting: Mount on the left or right handlebar to switch LED driving lights or fog lights without removing hands from grips. Scooter/ATV accessory control: Use to operate heated grips, USB chargers, or auxiliary devices while keeping controls centralized on the handlebar. Offroad use: Durable finish and protected circuitry make it suitable for ATVs used in dusty or wet conditions where robust components are required. Installation notes Confirm vehicle uses a 12V battery system before installing. Ensure handlebar grip diameter is between 22 and 23 mm (0.78'–0.90') for secure mounting. No builtin pilot lamp; add an external indicator if visual status feedback is needed. What makes it stand out Combination of aluminumalloy construction, anode blasting finish, handlebarspecific mounting, and builtin electrical protections provides a practical, longlasting control solution for 12V two and fourwheel vehicles.
