DMEX D1S HID Headlight Bulbs 8000K White-Blue 35W Pack of 2 — 3800 lm Quartz Anti-UV

DMEX D1S 8000K Xenon HID headlight bulbs are direct replacements for factory D1S HID units, delivering a crisp white-blue 8000K color temperature in a 35W xenon package (pack of 2).

These DMEX D1S bulbs are designed specifically for vehicles equipped with D1S factory HID systems and are not compatible with halogen headlamp assemblies. Constructed from 100% quartz anti-UV glass and filled with high-quality xenon gas, they aim to reproduce the look and brightness associated with OEM-type HID lamps while offering an 8000K color tone for a cooler white-blue appearance. This listing is for two bulbs (35W) and fits common D1S part numbers such as 66144, 66140, 85140 and 85415.

How do these DMEX bulbs differ from a standard D1S factory lamp?

The DMEX D1S bulbs use quartz anti-UV glass and a tungsten metal electrode to maintain stable arc performance. Their xenon fill and APL pills are selected to produce up to 3800 lumens in optimal conditions, which is positioned as a brighter output than many original standard bulbs. The 8000K color temperature also shifts light toward a whiter, slightly blue tint compared with lower-K HID options.

• 100% quartz anti-UV glass resists yellowing and lens damage.
• High-quality xenon gas and APL components for consistent arc.
• Rated up to 3800 lumens under ideal conditions.
• 8000K color temperature for a white-blue appearance.

Will these bulbs work in my car’s lighting system?

These bulbs are intended only as replacements for vehicles equipped with factory D1S HID systems. They are NOT compatible with halogen headlamp housings or systems that require halogen bulbs, even if hardware listings appear to match. Confirm your vehicle uses D1S ballast and socket types before ordering to ensure fitment.

• Fits vehicles that originally use D1S 35W HID bulbs (66144, 66140, 85140, 85415).
• Not for halogen headlamp assemblies—do not install in halogen sockets.
• May require compatible ballasts if aftermarket changes have been made.

What performance changes should I expect after installation?

In practical terms, DMEX specifies an increased irradiation distance compared with some baseline bulbs, which can extend visible road coverage under the right conditions. The cooler 8000K tint emphasizes contrast and a modern white-blue look, though perceived brightness and color depend on reflector/lens design and weather. No bulb can change legal beam patterns; use proper aiming and approved housings.

• Manufacturer notes up to a 50m increase in irradiation distance in certain setups.
• Appears brighter than some standard OEM bulbs with up to 3800 lumens listed.
• 8000K produces a white-blue aesthetic favored for modern styling.
• Maintain correct aim to avoid glare for other drivers.

How durable and safe are DMEX D1S bulbs?

DMEX builds these bulbs with quartz anti-UV glass to reduce degradation from UV exposure and uses tungsten electrodes intended for consistent performance. They are sold as a pack of two and include a 2-year warranty from the manufacturer for defects. Always handle HID bulbs carefully and avoid touching the quartz surface directly to preserve lifespan.

• Quartz anti-UV glass reduces lens and bulb wear from UV exposure.
• Tungsten electrode and xenon gas for stable arc operation.
• Pack of 2 bulbs with a 2-year manufacturer warranty for defects.
• Do not touch glass directly; allow ballast ignition system to remain untouched.

Who is this for? The DMEX D1S 8000K 35W bulbs are aimed at drivers with factory D1S HID systems who want a cooler white-blue look and a perceived boost in long-range illumination. They suit vehicle owners seeking OEM-style HID replacements with quartz anti-UV construction and a two-bulb warranty, but they are not appropriate for cars with halogen-only headlamp assemblies or owners who need strictly factory color-temperature matches.
