DMEX D4S HID Headlight Bulbs 6000K Cool White 35W Pack of 2 — 3800 lm, Quartz Anti-UV

DMEX D4S 6000K HID bulbs are direct replacements for factory D4S xenon headlights, delivering bright cool-white illumination and improved road visibility in a pack of two.

These DMEX D4S 35W HID bulbs are engineered as like-for-like replacements for vehicles equipped with factory D4S xenon systems. Built from quartz anti-UV glass and filled with high-quality xenon gas, they produce a crisp 6000K cool-white beam that reads as daylight on the road. These bulbs are not compatible with halogen headlamp systems—verify your vehicle uses D4S HID fittings before ordering.

How much brighter are these bulbs compared with standard D4S units?

DMEX D4S bulbs are designed to outperform many original factory bulbs in lumen output and beam consistency. They offer up to approximately 3800 lumens per bulb, which typically reads as a noticeable increase in on-road brightness and edge clarity.

• Rated up to 3800 lumens for stronger forward illumination.
• 6000K cool-white tone for contrast against road markings and signs.
• Quartz anti-UV glass reduces yellowing and maintains light quality.

Will these fit my car and how do I confirm compatibility?

These units are meant exclusively for vehicles that use D4S HID factory bulbs. They will not work in halogen headlamp housings even if a fitment tool lists compatibility—use your vehicle's manual or inspect the existing bulb to confirm D4S type.

• Replacement for factory D4S HID only — check the bulb code on your car.
• Not compatible with halogen systems or retrofit housings lacking xenon ballasts.
• Sold as a pack of two for axle replacements and balanced color output.

How durable and reliable are these DMEX HID bulbs?

Constructed with tungsten electrodes and premium APL ignition pills, the bulbs emphasize consistent arc stability and longer useful life. The quartz anti-UV glass resists heat and UV-induced degradation, helping preserve output and color balance over time.

• Quartz anti-UV glass for reduced discoloration and heat resistance.
• Tungsten metal electrode and high-quality xenon gas for stable light output.
• Backed by a two-year warranty for manufacturing defects.

What changes will I notice in real-world driving?

Beyond a whiter beam, the DMEX bulbs are tuned to extend usable illumination distance and clarify object contrast on the road. The manufacturer cites increased irradiation distance, which can enhance the visible stretch ahead under nighttime conditions when properly aligned.

• 6000K color temperature improves contrast for road signs and lane markings.
• Reported longer effective illumination range for earlier obstacle detection.
• Sold in matched pairs to reduce color mismatch between left and right beams.

Who is this for: Drivers with factory D4S xenon headlight systems seeking a cooler, brighter replacement bulb set that preserves OEM-style performance. Choose these bulbs if you want a like-for-like HID swap with improved lumen output and durable construction. Do not buy if your vehicle uses halogen bulbs or if you need an HID conversion kit—these are replacement D4S xenon bulbs only.
