HD Relay: 9006

Ensure maximum performance and reliability from your HID lighting system with the Morimoto HD Relay Harness H10. Designed to supply clean, stable power directly from your vehicle's battery, this premium relay harness eliminates voltage drops that can cause HID ballasts to flicker, misfire, or fail to ignite properly.

Unlike your vehicle's factory headlight wiring—which is designed to power standard halogen bulbs—the Morimoto HD Relay Harness provides the consistent voltage required for dependable HID performance in all driving conditions.

Why Use a Relay Harness?

A quality relay harness is one of the most important components of any HID conversion. Even the best HID bulbs and ballasts cannot perform properly if they aren't receiving stable battery voltage. The Morimoto H10 ensures reliable startup, brighter light output, and longer ballast life by bypassing the limitations of the factory headlight circuit.

Easy Plug-and-Play Installation

The Morimoto H10 is designed for a quick, hassle-free installation. No cutting or splicing is required, and the universal wiring layout provides enough length for installation on most passenger cars, SUVs, and trucks.

Simply connect the harness to your battery, plug it into your factory headlight connector, connect your HID ballasts, and you're ready to go.

Universal Compatibility

The H10 Relay Harness is compatible with nearly all aftermarket HID systems using industry-standard ballast connectors.

Ideal for:

• HID Low Beam conversions
• HID High Beam conversions
• HID Fog Light conversions

Please Note: Vehicles equipped with CANBUS electrical systems or pulsed Daytime Running Lights (DRLs) may require a Morimoto CANBUS or Mopar-specific harness for proper operation.

Dual Relay Fail-Safe Protection

Unlike many universal HID relay harnesses that use a single relay to power both headlights, the Morimoto H10 features dual sealed 40A relays, with one dedicated relay for each side of the vehicle. This fail-safe design helps maintain operation of one headlight should a relay ever fail.

Each relay features:

• Fully sealed weather-resistant housing
• Ribbed silicone upper and lower seals
• Integrated flyback diode for back-EMF protection
• Weatherproof connectors throughout the harness

This rugged construction provides dependable performance even in harsh weather, high humidity, and extreme temperatures.
