DMEX D4R HID Headlight Bulbs 6000K 35W - 2pc Xenon Replacement, 3800 lm Cool White

DMEX D4R 6000K Xenon HID headlight bulbs are a direct replacement pair designed for vehicles with factory D4R HID housings, delivering bright cool-white light and improved beam reach.

If your vehicle originally came equipped with D4R HID headlights, these DMEX 35W bulbs provide a like-for-like replacement engineered to work with the same ballast and reflector geometry. They use high-purity xenon gas and durable quartz glass to reproduce crisp 6000K cool-white output while maintaining the proper light cutoff pattern expected from D4R lamps. Note: these will not fit cars that use halogen headlamp systems.

How bright and what color temperature can I expect?

These DMEX bulbs produce a cool-white 6000K color, yielding a modern white-blue appearance similar to factory xenon lamps. The bulbs are engineered to reach up to approximately 3800 lumens per bulb under ideal conditions, giving a visibly brighter beam than many aging original bulbs.

• Color temperature: 6000K cool white for clear road contrast.
• Rated luminous output: up to ~3800 lumens.
• Power consumption: standard 35 watts per bulb for compatibility.
• Designed for xenon HID systems, not halogen sockets.

Will these fit my vehicle and the original HID system?

DMEX D4R bulbs are manufactured as direct replacements for factory D4R HID lamp modules and will work with the original ballasts and wiring when your car is equipped with D4R sockets. They are not compatible with halogen housings or systems labeled as halogen—even if online fit lists appear otherwise.

• Fitment: specifically for D4R HID housings and ballasts.
• Not compatible with halogen headlamp systems—do not attempt to force-fit.
• Plug-and-play where the vehicle originally used D4R bulbs.
• Check your owner’s manual or the existing bulb base to confirm D4R type before ordering.

What materials and durability features do these bulbs offer?

DMEX builds these D4R bulbs with 100% quartz anti-UV glass that resists discoloration and withstands high temperatures. Internal components include high-quality xenon gas, APL ignition pills, and tungsten electrodes to support consistent ignition and life span similar to OEM HID units.

• Optical envelope: quartz anti-UV glass to limit yellowing and heat damage.
• Fill gas: high-purity xenon for stable arc and color consistency.
• Electrodes: tungsten metal for robust electrode life.
• Pack quantity: two bulbs (left and right) for full axle replacement.

How does installing these bulbs affect visibility and reaction time?

By restoring bright, white xenon illumination, these bulbs extend effective illumination distance compared with worn-out lamps, which can help you see road details sooner. Manufacturer data indicates increased irradiation distance, which translates to additional seconds of reaction time at typical driving speeds.

• Reported increase in irradiation distance by roughly 50 meters (vehicle and conditions dependent).
• Estimated extra brake-reaction time of a few seconds at regular driving speeds.
• Improved contrast and color rendering at night compared with dimmed original bulbs.
• Maintains correct beam cutoff when used in proper D4R reflector/projector housings.

Who is this for: These DMEX D4R 6000K 35W xenon bulbs are intended for drivers whose cars originally used D4R HID headlamps and who want a like-for-like replacement with a cool-white appearance and solid lumen output. Choose these if you need a pair to restore factory HID performance, appreciate quartz anti-UV construction, and want a straightforward swap without changing ballasts. Do not buy if your vehicle uses halogen bulbs or non-D4R HID types.
