DMEX D1S HID Headlight Bulbs 4300K Warm White 35W — Pack of 2, Quartz Anti-UV Glass & 2-Year Warranty

DMEX D1S 4300K HID headlight bulbs are direct replacements for factory D1S xenon units, delivering warm-white 4300K light at 35W in a two-bulb pack.

These DMEX D1S bulbs are engineered for vehicles equipped with factory D1S HID systems—not halogen setups—and offer a balance of color temperature, output and longevity. Built with quartz anti-UV glass, premium xenon gas and robust electrodes, the set claims brighter illumination than many stock bulbs and a two-year warranty for peace of mind. Use them when your OEM D1S bulbs age, dim or fail and you want consistent warm-white light with reliable fitment in compatible HID assemblies.

How do these DMEX D1S bulbs compare to original factory HID bulbs?

DMEX designs these D1S replacements to match factory form factor and electrical requirements while enhancing perceived brightness and durability. They use high-grade xenon fill and APL pills to help sustain light output and color stability over the bulb’s life.

• Rated at up to 3800 lumens, typically brighter than many OEM D1S units.
• 4300K warm-white color for neutral visibility without excessive blue tint.
• Quartz anti-UV glass resists heat and lens damage over time.

Will these fit my car’s headlight assembly?

Only install if your vehicle uses factory D1S HID bulbs; these will not work in halogen headlamp systems even if some fit guides claim compatibility. Proper fitment requires the D1S bulb base and HID ballast designed for xenon ignition.

• Direct replacement for D1S sockets and ballasts (66144, 66140, 85140, 85415 references).
• Not compatible with halogen bulb housings or connectors.
• Check vehicle manual or existing bulb stamping to confirm D1S type before ordering.

What performance and safety features do these bulbs offer?

DMEX D1S bulbs include materials and construction aimed at steady output and reduced lens wear. The stated improvements focus on visibility distance and reaction time benefits from increased illumination, while the quartz glass helps maintain optic durability.

• High-quality xenon gas and tungsten electrodes for reliable arc stability.
• Quartz anti-UV glass reduces UV transmission that can fog or damage headlamp plastics.
• Manufacturer notes up to 50m increased illumination reach compared with some older bulbs.

How long will these bulbs last and what warranty is included?

Longevity depends on driving conditions and usage, but DMEX offers a two-year warranty to cover defects or premature failure. Proper handling and avoiding skin oils on the glass during installation help maximize service life.

• Pack of 2 D1S 35W 4300K replacement bulbs included.
• Two-year warranty from DMEX for manufacturing defects.
• Follow recommended installation steps to prevent damage and preserve lifespan.

Who is this for: drivers with factory D1S xenon headlamp systems who want a warm-white 4300K replacement with improved perceived brightness and durable construction. These bulbs suit owners replacing aged or failed D1S units who need direct-fit parts, plus technicians and DIY installers familiar with HID ballast systems. Do not buy these for halogen housings—verify your vehicle uses D1S HID bulbs before purchasing.
