Super Decoder Harness KIt H13 (2 EA)

The ARC Lighting Super Decoder Harness Kit H13 is a two-unit set of advanced LED and HID headlight wiring harnesses engineered to eliminate error codes and flickering that occur when upgrading to modern lighting technology. This decoder harness kit solves a critical compatibility problem: when drivers retrofit high-intensity discharge or light-emitting diode bulbs into vehicles with stock wiring, the vehicle's onboard diagnostic system often interprets the different electrical signature as a fault condition, triggering check-engine lights and disabling the headlights entirely.

The H13 connector configuration makes this kit compatible with a wide range of domestic and imported vehicles that use dual-filament H13 bulb sockets. The Super Decoder technology conditions the power delivery to match the electrical signature expected by the vehicle's lighting control module, preventing error codes while allowing the full brightness output of LED or HID bulbs to reach the road. Installation integrates directly into the factory wiring harness without requiring permanent modifications, enabling users to switch back to stock bulbs if needed without leaving traces. The two-unit quantity addresses both headlight positions in a single purchase.

This harness kit is essential for anyone upgrading to brighter lighting for improved nighttime visibility on trucks, SUVs, or passenger vehicles while maintaining factory diagnostics. Off-road enthusiasts, delivery drivers, and anyone operating in low-light conditions benefit from modernized headlight output without the troubleshooting burden of warning lights and automatic shutdowns. The compact profile—measuring 5 x 2 x 7 inches and weighing just 1.13 lbs for both units—fits neatly behind dashboard and headlight assemblies, minimizing installation complexity.
