Anti-Flicker: Low Beam

The Morimoto HD Anti-Flicker HID Relay Harness is the ultimate power solution for HID conversion kits installed on vehicles equipped with PWM (Pulse Width Modulation) headlight circuits. Designed to eliminate flickering, flashing, and unstable ballast operation, this premium relay harness delivers clean, consistent battery power while protecting your HID system with OEM-quality components and advanced relay technology.

Built with dual sealed relays, integrated anti-flicker capacitors, and heavy-duty automotive wiring, the Morimoto HD Relay Harness provides the reliability and performance expected from one of the industry's most trusted names in automotive lighting.

Eliminates PWM Flickering

Many modern vehicles use PWM-controlled headlight circuits, where the factory halogen bulbs receive power through a rapidly pulsing electrical signal. While halogen bulbs operate normally on this type of circuit, HID ballasts often respond by flickering, flashing, or failing to operate consistently.

The Morimoto HD Relay Harness features an integrated 4700uF capacitor that absorbs these pulsing signals and delivers smooth, uninterrupted power to your HID ballasts.

Perfect for correcting:

• HID headlight flickering
• HID flashing
• Ballast instability
• PWM-related electrical interference
• Inconsistent HID startup

Independent Dual Relay Design

Unlike inexpensive relay harnesses that rely on a single relay to power both headlights, the Morimoto HD Harness utilizes one dedicated 40A relay for each side of the vehicle.

This fail-safe design offers several important advantages:

• Independent operation for each headlight
• Individual relay protection
• Increased system reliability
• Prevents complete lighting failure if one relay is damaged
• Easier troubleshooting and maintenance

Each relay is fully sealed and engineered for years of dependable performance.

Premium Weather-Sealed Construction

Every component of the Morimoto HD Relay Harness is built to withstand harsh automotive environments.

Premium construction includes:

• Fully sealed 40A automotive relays
• Integrated flyback diode for back-EMF protection
• Silicone-sealed relay housings
• Weatherproof electrical connectors
• Heavy-duty automotive-grade wiring
• Abrasion-resistant Techflex mesh sleeving
• Polished stainless steel relay mounting bracket

Whether you drive through rain, snow, heat, or road salt, this harness is built to provide reliable performance year-round.

Simple Plug-and-Play Installation

Installation is quick and straightforward with no cutting or splicing required.

The harness features:

• Direct plug-and-play connections
• Clearly labeled wiring
• Extra-long wire lengths for cars, trucks, and SUVs
• Battery-powered relay design for stable HID performance

Simply connect the harness between your factory wiring and HID ballasts, then attach the fused power lead to the battery for reliable operation.
