Heavy-Duty HID Battery Relay Harness with Integrated Load Resistors
The O-NEX HID Battery Relay Harness is the professional choice for stabilizing power and eliminating performance issues in aftermarket HID conversion kits. While many vehicles can run HIDs directly from the factory wiring, certain computer-controlled systems require this harness to provide a consistent, direct draw of power from the battery.
Common Problems This Harness Solves:
Flickering & Pulsing: Fixes light “stutter” caused by low or fluctuating electrical current.
Intermittent Operation: Solves the “one light out” or “fail-to-ignite” issues during startup.
Dashboard Error Codes: Built-in load resistors help bypass “Bulb Out” warnings in sensitive vehicles.
Low Light Output: Ensures your HID ballasts receive the full voltage required for maximum brightness.
Delayed Ignition: Eliminates slow-start issues by drawing power directly from the battery via a heavy-duty relay.
Features & Technical Specs:
Dual-Action Protection: Combines a 60A Relay and 50W 8-Ohm resistors for total system stability.
Industrial Build: Features a 20A safety fuse and high-temperature resistant wiring.
Voltage: 12V DC.
Load Resistors: Dual 50W 8RJ resistors (one for each side).
Relay Rating: Heavy-duty 60A / 12V DC.
Compatible Bulb Types: H1, H3, H7, H11, 9005, 9006 (requires connection to the HID bulb pigtail).
⚠️ Critical Safety & Installation Notes
1. Heat Warning: The load resistors generate high temperatures during use. Must be mounted to a metal surface. Do not mount on plastic, rubber, or painted surfaces to avoid heat damage or melting.
2. Fitment Requirement: This harness is designed for Single-Beam HID kits. You will need to use the power/input wires coming from your HID bulb to trigger the relay and connect back to your vehicle’s factory harness.
3. Vehicle Compatibility: Highly recommended for modern vehicles with CANBUS or Pulse Width Modulation (PWM) systems, including:
Domestic: Ford, Cadillac, Chevrolet, Chrysler, Dodge, Jeep.
Import: BMW, Mercedes-Benz, Hyundai, and more.
Why Choose the O-NEX Battery Harness?
Unlike standard “warning cancellers,” this harness protects your vehicle’s expensive factory wiring by using it only as a “signal” to turn the lights on. The actual power is drawn safely from the battery, preventing stress on your car’s electrical computer (ECU).
