Innovited D4S HID Xenon Headlight Bulbs 8000K Pack of 2 — White-Blue, IP67 Waterproof Metal Base

Innovited D4S HID Xenon 8000K replacement bulbs are a high-brightness, 2-piece set designed to replace factory D4S HID headlight bulbs for sharper, whiter-blue light in compatible vehicles.

These Innovited D4S xenon bulbs (pack of 2) fit vehicles that use D4S/66440/42402-series HID bulbs and deliver a cool 8000K color temperature. They are sold as bulb-only replacements — compatible with stock HID ballasts — and are not suitable for halogen- or LED-only headlamp systems. Built with an anti-UV coating, IP67-rated sealing, and a metal base for heat resistance, these bulbs aim to combine a long life with high perceived brightness in both high and low beam assemblies.

How bright and what color will these bulbs produce?

These Innovited D4S bulbs are rated to be significantly brighter than standard factory HID lighting and produce an 8000K color temperature with a white-blue tint. Expect a cooler, blue-leaning light compared with stock 4300K bulbs; they will appear whiter and more blue than warm xenon tones.

• Color temperature: 8000K (white with blue cast)
• Claimed brightness: up to 200% brighter than standard HID (per manufacturer)
• Reach full perceived brightness within a few seconds after ignition

Will these fit my car and how easy is installation?

These bulbs are made to be a 1:1 physical replacement for D4S-type HID bulbs and are intended to work with vehicles that already have D4S HID ballasts. Installation is a bulb-swap only process and typically takes about five minutes per side when access is straightforward.

• Fitment: replacement for D4S / 66440 / 42402 series bulb housings
• Installation: bulb-only swap; no ballast or wiring modification for compatible HID systems
• Note: not compatible with stock halogen or LED systems without appropriate HID conversion kit

How durable are these bulbs and what maintenance should I expect?

Innovited specifies an expected life of approximately 3,500 hours and incorporates an anti-ultraviolet coating to reduce color shift and dimming over time. A metal heat-resistant base and IP67 waterproof rating improve resistance to moisture and heat-related degradation.

• Rated lifespan: around 3,500 hours
• Protection: anti-UV coating and IP67 waterproof design
• Construction: high-temperature resistant metal base to reduce fogging or vapor damage

What should I check before ordering to avoid fitment issues?

Confirm your vehicle uses D4S HID bulbs from the factory, and ensure you need bulb-only replacements rather than an entire HID conversion kit. If you're unsure which bulb type your vehicle uses, check the owner's manual or contact Innovited customer support for guidance.

• Verify original bulb type: D4S / 66440 / 42402 / 42402WX compatible
• Check if your car already has HID ballasts — required for bulb-only replacement
• Contact seller if you have multiple headlamp assemblies or uncertain fitment

Who is this for? Drivers who want a cooler, more modern white-blue xenon appearance from their factory HID headlamps and who already have D4S-compatible ballasts will find this Innovited D4S 8000K pack useful. It’s aimed at vehicle owners seeking bulb-only replacements with higher perceived brightness and improved protection against UV, moisture, and heat — without changing ballasts or headlight housings. If you need a full conversion from halogen or LED, or require a warmer color temperature, consider the appropriate conversion kit or alternative color rating.
