They produce a brighter, whiter light color at 8000K and run at 35 watts, designed specifically to match the fit and electrical profile of stock xenon headlights. Installation is intended for vehicles already equipped with D4S or DS4 HID ballast systems; they are not compatible with halogen fixtures.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these bulbs compare to halogen lights?\u003c\/h3\u003e\n\u003cp\u003eCompared with typical halogen bulbs, these xenon HID units produce much higher lumen output and a cooler color temperature for improved nighttime contrast. They consume similar or slightly different wattage while delivering a visibly stronger beam pattern, helping make road signs and lane edges easier to spot under many conditions.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eOutput: up to ~3600 lumens versus ~800 lumens for halogen\u003c\/li\u003e\n  \u003cli\u003eColor: 8000K cool white-blue tone for clearer peripheral detail\u003c\/li\u003e\n  \u003cli\u003ePower: 35W operating power matching standard HID ballasts\u003c\/li\u003e\n  \u003cli\u003eLongevity: tungsten electrode design for longer, more stable light life\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these bulbs fit my car and how do I confirm compatibility?\u003c\/h3\u003e\n\u003cp\u003eThese bulbs are specifically made as replacements for D4S\/DS4 xenon sockets; fitment depends on your vehicle’s headlight trim and existing HID system. Before purchasing, check your owner’s manual, inspect the marking on your current bulb, or consult the vehicle’s part reference numbers to confirm the correct D4S\/DS4 style.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eReplacement part numbers referenced: 42402, 66440, 42402WX\u003c\/li\u003e\n  \u003cli\u003eOnly for vehicles with factory D4S\/DS4 HID ballasts—do not install in halogen housings\u003c\/li\u003e\n  \u003cli\u003eInspect bulb base and connector shape to verify plug-and-play fit\u003c\/li\u003e\n  \u003cli\u003eContact support if you see a fitment mismatch before installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat should I expect during installation and performance?\u003c\/h3\u003e\n\u003cp\u003eInstallation is typically straightforward for vehicles already equipped with compatible HID ballasts: remove the old D4S\/DS4 bulb and insert the Sinoparcel unit, securing the bracket and connector. Once fitted, expect faster warm-up than older xenon designs and a steady, intense beam output suited for high\/low beam setups where applicable.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePack contains 2 bulbs for axle replacement\u003c\/li\u003e\n  \u003cli\u003eDurable mounting bracket for secure fit and reduced moisture ingress\u003c\/li\u003e\n  \u003cli\u003eDesigned to minimize short-circuit and leakage risks through improved housing\u003c\/li\u003e\n  \u003cli\u003eProduces a stable beam with reduced flicker compared to worn bulbs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eAre there care tips or limitations I should know?\u003c\/h3\u003e\n\u003cp\u003eHandle HID bulbs carefully and avoid touching the glass with bare hands; oils can shorten life or affect beam quality.

Drivers who need a direct OEM-style xenon replacement for D4S\/DS4 headlight systems and want a cooler 8000K color tone with higher lumen output than halogen will benefit. This pack of two suits those replacing both sides together, performing maintenance on older HID headlights, or restoring factory-style performance with a bright, stable light source—provided the vehicle already uses xenon ballasts and accepts D4S\/DS4 bulbs.\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 bulbs compatible with halogen headlight housings?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. These Sinoparcel bulbs are designed only for vehicles with D4S\/DS4 xenon ballasts, not halogen housings.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What color temperature and wattage do these bulbs use?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: They run at 35W and produce an 8000K cool white-blue light color for increased contrast.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Sinoparcel","offers":[{"title":"Default Title","offer_id":55166245536087,"sku":"B01LXO01PB","price":36.21,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1050\/1524\/7191\/files\/sinoparcel-d4s-front-view-pack-of-2.jpg?v=1790365644","url":"https:\/\/britishgarage.co.uk\/products\/sinoparcel-d4s-xenon-hid-headlight-bulbs-8000k-35w-pack-of-2-oem-style-bright-white-blue-beam","provider":"British Garage","version":"1.0","type":"link"}
