D3S Xenon HID Headlight Bulbs for OEM Projector-Based Lighting Systems

This Underground Lighting collection is dedicated exclusively to D3S Xenon HID headlight bulbs and D3S-specific electrical components, engineered for factory-installed HID projector headlight systems. The D3S bulb is an OEM high-intensity discharge (HID) light source, producing light through an electric arc inside a xenon-filled quartz arc chamber, rather than a filament or diode.

Unlike older D1S bulbs, the D3S Xenon HID bulb is mercury-free, making it RoHS- and ECE R99–compliant and mandatory in many late-model vehicles. D3S bulbs operate at 42V AC and 35W nominal power, requiring a D3-specific HID ballast. Although D3S bulbs may appear physically similar to D1S, they are not electrically interchangeable due to the voltage difference (42V vs 85V) and must never be cross-installed.

All D3S bulbs use a PK32d-5 indexed metal base with an integrated high-voltage igniter, which simplifies wiring and ensures precise arc alignment within projector-only headlight housings. Because beam cutoff and glare control are handled by the projector optics, D3S bulbs are not suitable for reflector housings.

This collection includes:

  • D3S Xenon HID Bulbs (35W) in 6000K white and 8000K white with blue tint
  • D3S 5000K Extreme White Xenon HID Bulbs, optimized for higher usable road illumination with a cleaner white beam
  • Aftermarket D3S Ballast (35W), designed specifically for 42V AC D3S systems

Typical light output for D3S bulbs falls within ~3200–3500 lumens per bulb, delivering approximately 3× the brightness of halogen headlights when installed in factory projector housings. While 4300K remains the OEM standard for maximum usable light, aftermarket options in 5000K, 6000K, and 8000K allow drivers to adjust beam appearance, with higher Kelvin ratings trading some lumen efficiency for style.

D3S bulbs are most commonly used as primary low-beam headlights, often within bi-xenon projector systems that use a mechanical shutter to provide high-beam functionality. Proper twist-lock installation, ballast matching, and vehicle-specific fitment verification are essential to maintain beam accuracy, electrical stability, and road legality.

This collection supports OEM replacement, easy to install and performance-oriented upgrades for vehicles from Audi, BMW, Mercedes-Benz, Lexus, Ford, and other manufacturers that specified D3S HID systems from the factory.
D3S Xenon bulbs are factory high-intensity discharge (HID) headlight bulbs that use xenon gas and an electric arc to produce bright, white light. Unlike traditional halogen bulbs with glowing filaments, these HID lights deliver superior illumination that closely resembles natural daylight.

These bulbs are designed specifically for D3S headlight housings, so they’re perfect for upgrading or replacing factory-installed HID systems. When you want to boost your vehicle's lighting appearance and increase your visibility in dark or rainy , cold, foggy & snowy weather conditions, D3S Xenon HID bulbs are an excellent solution.

Why Choose Underground Lighting D3S Xenon HID Headlight Bulbs?

  • ~3× Higher Brightness Than Halogen Headlights

    D3S HID bulbs produce approximately 3200–3500 lumens, compared to ~1200 lumens from halogen, significantly improving forward visibility and night-time driving safety.

  • Mercury-Free, Eco-Compliant HID Technology

    D3S bulbs contain no mercury, meeting RoHS and ECE R99 standards, making them environmentally safer than older D1S and D2S HID formats.

  • Precision Beam Control in Projector Optics

    The arc focal point of a D3S bulb is engineered specifically for projector housings, producing a sharp cutoff and controlled light distribution with reduced glare.

  • OEM-Standard 35W Power With 42V Stability

    Operating at 35W and 42V AC, D3S bulbs deliver stable brightness and controlled heat output, protecting headlight housings from thermal stress.

  • Multiple Kelvin Options for Function or Appearance

    5000K: Neutral white with strong road contrast
    6000K: Daylight white, balanced visibility and style
    8000K: White-blue aesthetic with reduced usable lumens

  • Direct Plug-In Replacement for Factory D3S Systems

    D3S bulbs are plug-and-play replacements for OEM D3S setups, requiring no wiring modifications when paired with the correct D3-specific ballast.

How to Choose the Right D3S Xenon Bulbs for Your Vehicle

When you're shopping for D3S Xenon HID bulbs, you need to make sure you’re choosing the right option for your car or truck. Replace those dull, yellow factory-grade lights with high-quality upgrades that perfectly match your vehicle's needs. Here's how to gurantee you get the perfect fit:

  1. Check Your Vehicle’s Manual: Check that your car uses D3S bulbs by looking at your owner’s manual or inspecting the base of your existing headlight bulb.

  2. Use Our Vehicle Finder Tool: Enter your vehicle’s make, model, and year into our finder tool to confirm compatibility. This ensures you select the right D3S headlight bulbs for your specific vehicle.

  3. Look for Canbus Compatibility: If your vehicle has a complex electrical system, look for Canbus-compatible D3S light bulbs to prevent flickering or error codes.

Whether you’re upgrading your headlights or replacing a burnt-out bulb, if you're unsure which product is best for your car or truck after reviewing the options, our professional representatives are ready to assist you through phone, email, or instant chat.

D3S Xenon High Intensity Discharge Headlights FAQs

Before beginning the installation, prioritize safety. Park your vehicle in a well-lit and secure area. Disconnect the vehicle's battery to avoid electrical shocks, and allow any existing bulbs to cool down to prevent burns: 

  • Locate the Bulb Housing: D3S Xenon Bulbs are typically within the headlight assembly's protective casing. You may need to remove a cover or panel at the back of the headlight housing to access the bulb.
  • Remove the Old Bulb: Carefully twist and disconnect the old D3S bulb from its socket. Avoid touching the bulb's glass surface with your bare hands, as oils from your skin can damage the bulb and reduce its lifespan.
  • Install the New D3S Xenon Bulb: Align the new D3S Xenon bulb’s base with the socket and twist it securely into place. Make sure that it is properly seated to prevent moisture or debris from entering the headlight housing.
  • Reassemble and Test: After installing the new bulb, reassemble the headlight housing and any covers or panels you removed. Reconnect the vehicle's battery and test the headlights to confirm that the D3S Xenon bulbs are functioning correctly.

This straightforward installation will secure optimal performance and longevity for your new D3S Xenon bulbs. If you're unsure or encounter issues, consult your vehicle's manual or seek professional installation assistance.

LED D3S bulbs are a downgrade from HID Xenon bulbs in projector headlights. They cannot project light as far as HID bulbs because LEDs produce a wider beam pattern, while HIDs create the focused beam that projector headlights need for efficient light reflection.

Replacing D3S HID xenon bulbs with LED alternatives in projector headlights will significantly reduce visibility beyond 30 feet, whereas HID bulbs maintain superior illumination for at least 100 feet.

Yes, HID headlights use Xenon Gas, unlike traditional Halogen bulbs. HID headlights are popular because of their unmatched brightness and durability. With HID Xenon bulbs, the Xenon Gas passes over an electrical charge, which gives these innovative bulbs the ability to burn much more brightly than factory-standard filament glowing bulbs.
