High-Intensity Xenon HID Replacement Bulbs for Factory HID Systems

OEM-spec Xenon HID headlight bulbs are designed for vehicles that use factory-installed HID lighting systems such as sedans, SUVs, and trucks. Unlike LED conversion kits, these bulbs are designed to replace existing HID bulbs directly. They also restore the original beam pattern, color quality, and proper lighting performance when old bulbs become dim, worn, or change color over time.

Underground Lighting covers both OEM and conversion applications. D-Series Xenon bulbs, including (D1S, D2S, D3S, D4S, D2R, D5S), are designed for vehicles equipped with OEM HID ballasts. While H-Series HID replacement bulbs, including (H1, H3, H4, H7, H8, H9, H10, H11, H13, 9004, 9005, 9006, 9007, 9012, 5202), are used in aftermarket HID conversion kits.

All bulbs operate on 35W nominal power and generate 2,800-3,500 lumens per bulb, making them up to 3x brighter than halogen headlights. Available color temperatures range from 4300K OEM white to 5000K extreme white and 6000K crisp white, giving drivers precise control over visibility, contrast, and overall visual appearance.

Built around gas-discharge, arc-based HID technology, these bulbs create light when an electrical arc passes through xenon gas inside a quartz arc tube. The result is intense, long-throw illumination ideally suited for projector headlight housings. Choose the best HID for your vehicle and explore our premium collection now.

Why Choose Xenon HID Headlight Bulbs for Cars, SUVs & Trucks

  • Up to 3× Brighter Than Halogen

    Xenon HID bulbs engineered at Underground Lighting produce 2,800–3,500 lumens per bulb, delivering a significantly more forward light and longer beam throw compared to 900–1,200-lumen halogen bulbs.

  • Superior Long-Range Visibility

    HID arc-based light output in Underground Lighting Xenon HID systems creates a dense, focused hotspot, improving highway visibility and reaction distance at speeds above 60 mph, especially in projector housings.

  • OEM Beam Pattern Accuracy

    Underground Lighting D-Series HID bulbs are designed to match factory focal points, preserving cutoff sharpness and minimizing glare when installed in the correct OEM projector or reflector housing.

  • Consistent Performance at 35W

    Standardized 35W operation balances brightness, thermal control, and ballast longevity, making Underground Lighting HID systems electrically stable for long-term use.

  • 2,000–3,000-Hour Service Life

    Compared to halogen bulbs (400–1,000 hours), Underground Lighting HID bulbs last 2–5× longer, reducing replacement frequency in daily-driven vehicles.

  • Factory-Correct Replacement for Legal Compliance

    Designed for factory HID applications, Underground Lighting OEM replacement bulbs help preserve DOT/ECE approved beam geometry and proper light distribution. This reduces the risk of excessive glare, poor beam control, and compatibility issues often caused by improper retrofit installations.

How to Find Out Which HID Replacement Bulbs You Need

We’re Underground Lighting’s experts who help you find the perfect HID headlight bulbs for your vehicle. Whether you’re upgrading for the first time or replacing existing HIDs, finding the correct bulb size is quick and simple.

Check your current HID bulb number

Look for the part number printed on your existing bulb base or metal housing. Common factory HID bulb sizes include D1S, D2S, D2R, D3S, D4S, and D5S. HID conversion kits may use bulb sizes such as H7, H11, 9005, 9006, 9007, or 9012.

  • Confirm factory HID vs. HID conversion kit

If your vehicle has xenon HID headlights from the factory, you will usually need a D-Series HID bulb. If you have an upgraded vehicle with an aftermarket HID kit, you may need an H-Series or 9000-Series HID replacement bulb.

  • Match the bulb to your ballast

HID bulbs need a compatible ballast to start and regulate light output. Choose a bulb that matches your ballast type, wattage, and connector style. Factory HID systems already have ballasts, while conversion kits use external ballasts.

  • Choose the right HID color temperature

For most drivers, 4300K to 6000K is the best range. 4300K gives an OEM-style white output, 5000K gives a clean white look, and 6000K gives a crisp modern white appearance. Higher Kelvin ratings are more style-focused.

  • Replace HID bulbs in pairs

HID bulbs can dim and color-shift over time. Replacing both sides together can maintain brightness, color, and beam appearance across the vehicle's front.

HID Headlight Bulbs FAQs

At Underground Lighting, HID headlight replacement bulbs usually cost around $40 to $200+ per pair, depending on the bulb type, color temperature, and whether the bulb is for a factory HID system or an aftermarket HID conversion kit.

Common price factors include HID size (e.g., D1S, D2S, D3S, D4S, H11, 9005, or 9006), Kelvin color temperature, and whether the bulb is designed for OEM xenon headlights. Factory-style D-series HID bulbs are slightly more expensive than basic replacement bulbs because they are made to work with specific HID housings and ballast systems.

An HID bulb, also known as a high-intensity discharge bulb, is a headlight bulb that produces light from a xenon gas arc instead of a halogen filament. They are commonly used in factory xenon headlight systems and HID conversion kits because they can produce strong forward light output with a bright white appearance.

Ballast is used to create and regulate an electrical arc inside the bulb. This arc lights the xenon gas and metal salts inside the capsule, producing the bright light output that HID headlights are known for. Because of this design, HID bulbs require a compatible ballast to operate.

A D2S HID bulb is a factory-style xenon HID bulb commonly used in projector headlights. The “S” usually indicates it is designed for shielded projector-style HID optics. D2S bulbs do not have an integrated igniter, so they must be used with the correct D2S-compatible ballast and headlight system.

The main difference between D1S, D2S, D3S, and D4S HID bulbs is that they are not interchangeable. They come with different bases, igniter designs, voltage requirements, and ballast compatibility. D1S and D3S bulbs have an integrated igniter, while D2S and D4S bulbs do not. Always replace your HID bulb with the exact bulb type listed for your vehicle.

D1S and D2S HID bulbs are different and should not be swapped. They have different base designs and electrical requirements, so using the wrong bulb can cause fitment problems, ballast issues, or headlight failure. Always match the exact HID bulb number printed on your current bulb or listed in your owner’s manual.

Many HID headlight bulbs can last 2,000 to 3,000 hours or more, depending on bulb quality, ballast condition, driving habits, heat exposure, and how often the headlights are used. HID bulbs can also dim or color-shift over time, even before they completely stop working.

HID bulbs should usually be replaced in pairs because they dim and change color as they age. Replacing both sides can maintain brightness, color temperature, and beam appearance across the vehicle's front.

For most drivers, 4300K to 6000K is the best HID color temperature range. 4300K is close to many OEM HID systems and provides strong, usable road light. 5000K gives a clean white look, while 6000K has a cooler white appearance. Higher Kelvin options look bluer or purpler but may reduce usable road visibility.

Yes, HID bulbs need a compatible ballast to ignite the xenon arc and regulate power. Factory HID vehicles already have ballasts installed, while HID conversion kits include or require external ballasts. If your HID bulb is flickering or not turning on, the ballast may also need to be checked.

Yes, HID bulbs can be used in projector headlights if they are designed for HID bulbs or with the correct HID conversion setup. Projector housings help control the beam pattern and reduce glare. Always confirm the correct bulb type, ballast compatibility, and local lighting rules before installing HID bulbs.

To install HID headlight bulbs, turn the vehicle off, let the headlights cool, remove the headlight dust cover, disconnect the old bulb, and carefully install the matching HID replacement bulb without touching the glass. Make sure the bulb is seated correctly and the connector is secure. If your vehicle uses a tight headlight assembly, professional installation may be easier.
