H49003 XTR HID Harnesses

The XenonDepot Premium HID Relay Harness Kit is engineered to deliver stable battery power to your HID conversion kit while eliminating flickering, strobing, and inconsistent ballast operation. Constructed with sealed relays, weather-resistant fuse holders, and premium tinned copper connectors, this harness is built to withstand harsh automotive environments while providing reliable HID performance for years to come.

Designed for vehicles equipped with CANBUS or sensitive factory electrical systems, this relay harness ensures your HID ballasts receive the clean, consistent voltage required for maximum light output and dependable operation.

Reliable Power for HID Systems

Many modern vehicles use advanced electrical systems that can interfere with aftermarket HID conversions, causing flickering, flashing, or intermittent startup. By drawing power directly from the vehicle's battery, the XenonDepot relay harness provides a stable power source while using the factory headlight circuit only as a trigger.

This helps eliminate common HID issues such as:

• Flickering headlights
• Strobing fog lights
• Inconsistent ballast ignition
• Voltage fluctuations
• CANBUS-related electrical interference

Independent Dual Harness Design

Unlike many relay harness kits that use a single relay for both headlights, the XenonDepot kit includes two complete relay harnesses—one dedicated harness for each side of the vehicle.

This premium design provides:

• Independent fused protection for each HID ballast
• Increased system reliability
• Protection against total system failure if one relay or fuse is damaged
• Easier troubleshooting and maintenance
• Improved electrical safety

Each ballast operates on its own dedicated, fused circuit for maximum reliability.

Premium Automotive Construction

Manufactured using high-quality automotive components, every harness is designed for long-lasting performance under demanding driving conditions.

Premium construction includes:

• Fully sealed automotive relays
• Weather-resistant sealed fuse holders
• Tinned copper electrical terminals
• Heavy-duty automotive-grade wiring
• Corrosion-resistant electrical connections

These components provide excellent durability against moisture, heat, vibration, and road debris.

Easy Plug-and-Play Installation

Installation is quick and straightforward with no cutting or splicing required. The harness connects between your factory headlight or fog light wiring and your HID ballasts while drawing power directly from the battery, reducing the load on your factory wiring and ensuring reliable HID performance.
