DMEX D1S HID Headlight Bulbs 6000K Cool White — Pack of 2, 35W 3800lm (Fits D1S 66144/66140/85140/85415)

DMEX D1S HID Headlight Bulbs are direct replacements for factory D1S xenon systems, delivering cool-white 6000K light and up to 3800 lumens for clearer road visibility.

These DMEX D1S bulbs (35W, 6000K) are engineered as like-for-like replacements for vehicles equipped with factory D1S HID systems. Built with quartz anti-UV glass, high-grade xenon gas and tungsten electrodes, they’re intended to restore bright, neutral white illumination without modifying your original headlamp housing. Note: these bulbs fit D1S HID fixtures only and will not work in vehicles that use halogen bulbs.

Will these bulbs fit my car's headlight system?

These DMEX D1S bulbs are size- and type-specific replacements meant for factory D1S HID sockets. They won’t function in halogen housings or non-D1S HID ballasts, so verify your vehicle’s bulb type before ordering.

• Not compatible with halogen headlamp assemblies.
• Check your owner’s manual or existing bulb marking to confirm D1S type.

How bright and what color temperature do these bulbs provide?

DMEX D1S bulbs produce a cool white light at 6000K, giving a crisp xenon appearance that balances clarity and contrast. Rated up to 3800 lumens, they’re designed to match or exceed many original HID outputs for improved road illumination.

Are these bulbs durable and reliable for daily driving?

What practical benefits can I expect after replacing with DMEX D1S bulbs?

Replacing worn or dull D1S HID bulbs with DMEX models can restore a sharper, more uniform beam pattern and tonal consistency with other xenon lighting. In many installations users report a perceptible improvement in beam reach and clarity compared with aged bulbs, helping you better see road markings and obstacles at night.

• Restores crisp xenon-white light and uniform beam pattern.
• Improves perceived contrast and object definition during night driving.
• Pack of two ensures both headlights match in color and intensity.

Choose DMEX D1S if you need bulbs that match D1S socket specifications, provide bright xenon-white illumination, and come with quartz anti-UV construction and a two-year warranty.
