Built with a resistor-and-capacitor error-free design inside a heavy-duty metal case, this accessory stabilizes current to LED bulbs so they operate reliably with modern vehicle on-board computers. The kit is designed specifically for H4\/9003 LED bulbs and fog lights, providing a practical fix for flicker, false bulb-out warnings, and audio interference that can occur after LED conversion. This is an add-on accessory only — not a complete headlight assembly — and is intended for use with LED systems rather than HID setups.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this harness stop flickering after LED conversion?\u003c\/h3\u003e\n\u003cp\u003eThe Xprite canbus decoder smooths and regulates the electrical signal between your vehicle and LED bulb. Inside, the resistor-capacitor circuitry reduces voltage spikes and corrects low-load detection issues so the bulb receives steady power.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIntegrated resistor and capacitor network prevents rapid voltage changes.\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty housing dissipates heat for consistent performance.\u003c\/li\u003e\n  \u003cli\u003ePack of two units covers both headlight plugs for H4\/9003 setups.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill it clear dashboard OBC errors and radio noise?\u003c\/h3\u003e\n\u003cp\u003eYes — for most vehicles the decoder prevents false error messages and reduces EMI (electromagnetic interference) that causes radio static.

The Xprite Reflex Series H4\/9003 Canbus decoder is ideal for drivers who have upgraded to H4\/9003 LED bulbs and need a reliable way to eliminate flicker, false dash warnings, or radio interference. It’s a practical solution for DIY installers, mechanics, and aftermarket lighting shops wanting a compact, durable accessory that improves LED behavior without complex wiring. If you require an entire headlight assembly or use HID systems, consider products designed for those applications instead.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this decoder work with HID headlight systems?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No, this Xprite decoder is designed for LED H4\/9003 bulbs only and is not compatible with HID systems.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do I need to splice my vehicle wiring to install it?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Usually no — the Reflex Series is plug-and-play for most H4\/9003 setups, but check fitment and connector access first.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Xprite","offers":[{"title":"Default Title","offer_id":48086303899806,"sku":"B07SGCHF5B","price":42.48,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/xprite-h4-9003-front-view-connector.jpg?v=1785894516","url":"https:\/\/northtrailauto.ca\/products\/xprite-h4-9003-canbus-decoder-anti-flicker-harness-pack-of-2-resistor-capacitor-load-stabilizer","provider":"North Trail Auto","version":"1.0","type":"link"}
