MotoCycle: Dual Output (H4)

The Morimoto MotoCycle H4 Dual Output Bi-Xenon HID Relay Harness is purpose-built for motorcycle HID and Bi-Xenon projector installations, delivering the stable battery voltage required for dependable lighting performance. Unlike factory motorcycle headlight circuits, which are designed to power standard halogen bulbs, HID ballasts require a clean and consistent power source. By drawing power directly from the motorcycle's battery, this relay harness eliminates voltage fluctuations, improves reliability, and helps maximize the lifespan of your HID components.

Designed Specifically for Motorcycles

Unlike universal automotive relay harnesses, the MotoCycle H4 harness is engineered exclusively for motorcycles. The wiring lengths and connector layout are optimized to fit within motorcycle fairings and compact chassis, providing a clean installation without excessive wiring or unnecessary modifications.

Whether you're upgrading a sportbike, touring motorcycle, cruiser, or adventure bike, this harness is designed to simplify installation while delivering professional-grade results.

Stable Power for HID Systems

The MotoCycle relay harness supplies consistent battery voltage directly to your HID ballasts, ensuring fast ignition, stable light output, and reliable performance. This helps prevent flickering, voltage drops, and premature ballast failure that can result from the fluctuating electrical systems commonly found on motorcycles.

Dual Output Bi-Xenon Design

Designed specifically for H4 (9003) Bi-Xenon applications, this harness powers two HID ballasts and both high beam solenoids from a single factory H4 trigger input. It is the ideal solution for motorcycles equipped with dual reflector headlights or custom dual Bi-Xenon projector retrofit systems.

Perfect for:

• Dual Bi-Xenon Projector Retrofits
• Dual HID Conversion Kits
• H4 / 9003 Motorcycle Headlight Upgrades
• Dual Reflector Motorcycle Headlights

Premium OEM-Quality Construction

Built to Morimoto's renowned quality standards, the MotoCycle harness features heavy-duty Techflex braided sleeving that protects the wiring against heat, abrasion, moisture, and vibration. A durable black anodized relay housing provides superior weather resistance while maintaining a clean OEM-style appearance when installed behind your motorcycle's fairings.
