Description

Electrical gremlins are frustrating, but often the fix is a simple, plug-and-play relay replacement. Hyosung uses this specific blue/black relay across a wide range of models for two main jobs: switching the high-draw headlights or powering the vital electric fuel pump on EFi bikes. As a common wear item, replacing this simple component with our Japan aftermarket unit is a quick maintenance win.

🔧 Install Tips

Safety First: Always disconnect the battery negative terminal before pulling out old electrical components.
Location: Relays are often tucked under the seat or behind side fairings. Consult your owner’s manual or our forums to locate the exact relay you need to replace.
Check the Click: A healthy, installed relay should make a distinct “click” sound when the ignition is switched on (for fuel pumps) or when headlights are activated.
