Heavy-Duty H4 Projector Relay Wiring Harness

KSh 2,500.00

Ensure stable power delivery and seamless high/low beam switching for your custom lighting setup. This plug-and-play relay wiring harness safely draws power directly from your vehicle’s battery, protecting your factory electrical system from voltage spikes and current overloads.

Description

Take the guesswork and risk out of upgrading your automotive lighting. This premium Bi-LED and HID projector relay harness is designed to provide clean, isolated power to aftermarket high-performance headlights. By drawing current directly from the battery via a dedicated heavy-duty relay controller rather than relying on thin factory wiring, it eliminates common retrofitting issues like flickering lights, one-sided ignition failures, and dashboard error codes.

Key Features:

  • Smart Relay Controller Box: Features an integrated control unit that safely manages the electronic signals required to instantaneously actuate dual-beam (high/low) internal projector shutters.
  • Inline Weatherproof Fuse: Equipped with a rugged, moisture-sealed inline fuse holder (with a pre-installed automotive blade fuse) to deliver crucial over-current protection to your expensive lighting components.
  • Plug-and-Play Connectors: Designed with standard male/female quick-disconnect plugs and weatherproof rubber seals to allow effortless integration into your vehicle’s existing headlight triggers.
  • Thick Protective Looming: Wrapped entirely in a high-grade, fluid-resistant black PVC protective sleeve that shields the internal wiring copper from extreme engine bay heat, friction, and moisture.
  • Universal Dual-Light Output: Provides long-reaching leads to easily route power to both the driver and passenger side headlight assemblies from a single battery source point.
