Kuryakyn LED Battery Gauge Universal Chrome - 4219

The Kuryakyn LED Battery Gauge Universal Chrome (Part #4219) is a compact, chrome-finished voltage monitor designed for any 12-volt charging system — making it a versatile upgrade for motorcycles, Harley-Davidson models, metric bikes, cars, trucks, and even riding lawn mowers. Whether you're building out your Harley dashboard or adding a functional accessory to a custom metric cruiser, this LED battery gauge gives you an at-a-glance read on your charging system's health so you're never caught off guard by a failing battery on the road.

Key Features & Benefits

• LED Array Voltage Display: An array of LEDs indicates the operating voltage of your 12V charging system in real time, letting you spot charging issues before they leave you stranded.
• Automatic Daylight Brightness Sensor: A built-in daylight sensor automatically adjusts LED brightness to match ambient lighting conditions — easy to read in direct sunlight and not blinding at night.
• Universal 12V Fitment: Designed for all 12-volt charging systems, this gauge fits motorcycles regardless of manufacturer — Harley-Davidson, Honda, Yamaha, Kawasaki, Suzuki, and beyond — as well as cars, trucks, and other 12V vehicles.
• Chrome Finish: The polished chrome housing integrates cleanly with classic and custom motorcycle aesthetics, particularly popular on Harley-Davidson builds where chrome accessories are a staple.
• Functional Charging System Monitor: Rather than relying on a simple warning light, this gauge lets you monitor your system's operating voltage continuously, so you can catch a weak alternator or aging battery early.
