The Xprite Reflex Series Canbus Anti-Flicker Kit for H4\/9003 is engineered as an inline adapter that corrects those signals so most LED bulbs behave like stock lights. It’s a compact, heavy-duty unit intended as an accessory for LED bulbs — not a replacement headlight assembly — and installs without cutting or splicing on compatible vehicles.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this decoder stop flickering and error messages?\u003c\/h3\u003e\n\u003cp\u003eThe harness combines resistor and capacitor circuitry to mimic the electrical load originally expected by the vehicle. That stabilizes current flow and prevents transient drops that cause flicker, turnoffs when the engine starts, or OBC\/system warning codes.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eResistor\/capacitor error-free design to simulate factory load\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty outer case for improved heat dissipation\u003c\/li\u003e\n  \u003cli\u003eReduces radio and electronic interference by smoothing signals\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIs installation difficult and will it fit my H4\/9003 bulbs?\u003c\/h3\u003e\n\u003cp\u003eInstallation is designed to be plug-and-play with H4\/HB2\/9003 connector types—no cutting or soldering required in most applications.

It’s aimed at DIY installers, mechanics, and anyone seeking a non-invasive fix for electrical compatibility issues. Confirm your bulb type (H4\/9003) and ensure you have space in the headlamp area for the decoder’s housing before purchase.\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 work with HID headlights?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. This Xprite canbus decoder is designed for LED H4\/9003 bulbs and is not compatible with HID ballast systems.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do I need to cut or splice my vehicle wiring to install it?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No cutting or splicing is typically required; it uses a plug-and-play inline connection for most vehicles.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Xprite","offers":[{"title":"Default Title","offer_id":55167766135127,"sku":"B07SGCHF5B","price":40.67,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1050\/1524\/7191\/files\/xprite-h4-9003-canbus-decoder-front-view.jpg?v=1790393174","url":"https:\/\/britishgarage.co.uk\/products\/xprite-h4-9003-canbus-decoder-anti-flicker-harness-pair-plug-and-play-load-resistors-for-led-headlights","provider":"British Garage","version":"1.0","type":"link"}
