They require an AC-type ballast and are not compatible with halogen or reflector-style headlamps; fitment is specific to D4S-basis housings on many 2006–2016 IS variants. Built from quartz anti-UV glass, ceramic insulation, and stainless mounting hardware, the set comes as a pair and installs without cutting or modification.\u003c\/p\u003e\n\n\u003ch3\u003eWill these bulbs fit my Lexus IS250 or IS350 low beams?\u003c\/h3\u003e\n\u003cp\u003eIf your vehicle has factory D4S xenon low-beam headlamps (bi-xenon\/AFS), these are a direct replacement that plugs into the original socket.

Do not buy these bulbs for halogen or reflector headlamp variants, or for vehicles lacking compatible ballasts. If your goal is a direct-fit, brighter xenon low beam with modern color tone and reliable construction, this GTMOTO D4S pair is built for that application.\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: Do these fit halogen headlamps?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. These D4S xenon bulbs are only for factory HID\/bi-xenon low-beam housings, not halogen or reflector headlamps.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What ballast do I need?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: You need an AC-type ballast compatible with D4S 35W xenon bulbs; the car’s stock HID ballast typically works.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"GTMOTO","offers":[{"title":"Default Title","offer_id":48083076841630,"sku":"B0CQTKXPZJ","price":64.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/gtmoto-d4s-front-view.jpg?v=1785823758","url":"https:\/\/northtrailauto.ca\/products\/gtmoto-d4s-hid-bulbs-for-lexus-is250-is350-6000k-cool-white-pair-for-oem-xenon-low-beams","provider":"North Trail Auto","version":"1.0","type":"link"}
