DMEX D4S HID Xenon Headlight Bulbs Pack of 2 — 35W 8000K White-Blue, 3800 lm, Quartz Anti-UV

DMEX D4S 35W HID Xenon bulbs are OEM-style replacements that deliver bright 8000K white-blue light for vehicles equipped with factory D4S HID systems.

If your vehicle originally came with D4S HID headlights, these DMEX bulbs offer a direct-fit replacement designed to restore or upgrade your lighting with crisp, cool-toned illumination. They are NOT compatible with halogen headlamp systems—only with cars that use the D4S HID specification. Each pack contains two 35W xenon bulbs made from quartz anti-UV glass and backed by a two-year warranty.

How do these bulbs change visibility on the road?

The DMEX D4S 35W bulbs produce up to approximately 3800 lumens, offering a brighter, higher-contrast beam compared with many stock HID units. Their 8000K color temperature gives a white-blue appearance that can improve object definition in low-light situations without altering the vehicle’s original projector optics.

• Up to ~3800 lumens output for increased brightness.
• 8000K white-blue light for high contrast and a modern look.
• Quartz anti-UV glass resists yellowing and maintains clarity.
• Designed for direct fit in factory D4S housings to preserve beam pattern.

Will these bulbs work with my car?

Only use DMEX D4S bulbs in vehicles that came factory-equipped with D4S HID systems. They will not work correctly in halogen headlamp systems, and attempting to fit them into incompatible housings can produce poor beam pattern and potential electrical issues.

• Compatible with vehicles specified for D4S HID bulbs only.
• Not compatible with halogen-only headlamp systems.
• Confirm your bulb type in the owner’s manual or existing bulb label before purchase.
• Plug-and-play installation in properly equipped HID ballasts and sockets.

What materials and lifespan performance do these bulbs offer?

DMEX D4S bulbs use high-quality xenon gas and APL ignition pills combined with tungsten electrodes to deliver consistent light output. Constructed from 100% quartz anti-UV glass, they resist UV degradation and help maintain lumen output over time; the set includes a two-year warranty for added assurance.

• 100% quartz anti-UV glass for durability and long-term clarity.
• Xenon gas fill and quality electrodes for reliable ignition and steady output.
• Designed to increase irradiation distance by about 50 meters in ideal conditions.
• Two-year warranty covers manufacturing defects under normal use.

How difficult is installation and what should I check before swapping bulbs?

Installation is straightforward for anyone familiar with HID systems: remove the headlamp access cover, disconnect the old D4S bulb, and install the DMEX unit into the same socket. Always power down the vehicle and handle bulbs by the base—not the glass—and verify ballasts and connectors are the correct D4S type before fitting.

• Turn off power and allow cooling before handling bulbs.
• Handle by the base; avoid touching the quartz glass surface.
• Ensure existing ballast is compatible with D4S 35W xenon bulbs.
• Follow vehicle-specific access instructions for safe replacement.

Who is this for? DMEX D4S 35W HID bulbs suit drivers who own vehicles originally equipped with D4S HID lighting and want a brighter, cooler-toned replacement without modifying housing or wiring. They are ideal for owners seeking improved nighttime contrast and a refreshed factory-style look, provided the car uses D4S ballasts and sockets. If your vehicle uses halogen bulbs or non-D4S HID types, choose a product matched to that specification instead.
