With a cool white 6000K tint, multi-layer cooling and precision beam optics, they aim to reproduce an OEM-style beam while increasing on-road brightness. They come as a two-bulb set and are engineered for fast startup, stable temperature control, and straightforward installation into original HID ballasts.\u003c\/p\u003e\n\n\u003ch3\u003eHow quickly do these bulbs reach full brightness?\u003c\/h3\u003e\n\u003cp\u003eThese D3S units use instant-start circuitry that brings the light to full output almost immediately.

They are aimed at owners whose cars already use D3S HID assemblies and want faster startup, enhanced illumination, and improved thermal stability. Do not purchase if your vehicle uses halogen bulbs; confirm the D3S ballast type before ordering. Follow safe installation practices: allow old bulbs to cool, use gloves to avoid skin oils on the glass, and verify beam aim after fitting.\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: Are these TechWizHub D3S bulbs compatible with halogen sockets?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. These bulbs are direct replacements for D3S HID assemblies only and will not fit halogen sockets.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do I need to modify wiring or ballasts to install them?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No wiring changes are required if your vehicle has a D3S HID ballast; they are plug-and-play replacements.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"TechWizHub","offers":[{"title":"Default Title","offer_id":67584891224249,"sku":"B0FWJYWDQZ","price":167.27,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0822\/3765\/3177\/files\/techwizhub-d3s-front-packaging.jpg?v=1790457873","url":"https:\/\/redleafauto.ca\/products\/techwizhub-d3s-hid-replacement-bulbs-6000k-pack-of-2-30-000-lm-built-in-cooling","provider":"Redleaf Auto","version":"1.0","type":"link"}
