The KOSO HD-03 4-Piece Digital Gauge Kit is a high-performance Plug & Play cockpit upgrade engineered for Harley-Davidson Touring fairing models. Connecting directly into the factory wiring harness, this kit features dual-color LED backlighting—allowing riders to easily switch between red and blue displays with 5 brightness levels, along with a sleek "blacked-out" finish when the ignition is turned off.
The 4-gauge setup includes a 4-inch digital speedometer (0-299 km/h or 0-199 mph), a 4-inch tachometer (0-9,990 RPM) with gear position display and adjustable shift light, a 2-inch oil temperature gauge (up to 248°C / 400°F), and a 2-inch fuel level meter. Packed with comprehensive telemetry, it tracks average fuel consumption, remaining fuel range, voltage levels, and oil change maintenance schedules. Fully compatible with all OEM indicator lights (including ABS, Cruise Control, Security, and Engine Check).
