Product Overview: Custom H11 LED Headlight Relay Wiring Harness Kit

Maximize Your LED Headlight Performance & Ensure Plug-and-Play Safety

Our Custom H11 LED Headlight Relay Wiring Harness Kit is the essential upgrade for anyone installing aftermarket LED or high-performance headlight bulbs. This dedicated harness directly connects your headlights to your vehicle's battery, providing a stable, high-current power source that bypasses the vehicle's often restrictive factory wiring. This eliminates voltage drop, ensures your LEDs receive full power for maximum brightness, and protects your vehicle's sensitive electronics.

Key Features & Benefits:

• Eliminates Voltage Drop & Prevents Flickering: By drawing power directly from the battery through a high-quality relay, this harness delivers consistent, full voltage to your headlights. This results in optimal lumen output and eliminates the flickering common with LED installations on factory circuits.

• Plug-and-Play Installation: Designed specifically for H11 bulb sockets, our harness features OEM-compatible connectors for a seamless and secure connection to your headlights and the vehicle's original headlight plug. No cutting or splicing is required, preserving your vehicle's factory wiring.

• Robust Power Delivery & Safety: The harness is constructed with heavy-duty, thick-gauge copper wiring capable of handling the high in-rush current of powerful LEDs. An integrated waterproof in-line fuse and a high-amp relay provide critical protection against short circuits and electrical overloads.

• Durable, Engineered Construction: Built to withstand under-hood conditions, the harness features heat-resistant insulation, waterproof relay and connector housings, and professional-grade terminals to ensure long-term reliability and performance.

• Universal Vehicle Compatibility: While the H11 connectors are standardized, the vehicle-side connector can be customized or adapted to ensure compatibility with a wide range of car, truck, and SUV models.

Applications:

• Upgrading to High-Performance LED or HID Headlight Bulbs

• Resolving Flickering or Dimming Issues with Aftermarket Lights

• Off-Road and Utility Vehicles Requiring Maximum Illumination

• General Headlight Performance Enhancement for Any Vehicle
