This Underground Lighting collection focuses exclusively on D2-series Xenon HID headlight bulbs, including D2S, D2R, and D2C variants, engineered for OEM HID lighting systems and compatible aftermarket applications.
Let’s see what D2 HID bulbs are ?
35W high-intensity discharge lamps that produce light via an electric arc inside a xenon-filled quartz capsule, delivering substantially higher brightness and beam reach than halogen bulbs.
Core D2 Bulb Types Covered
- D2S HID Bulbs
Designed for projector headlight housings, D2S bulbs use a P32d-2 keyed metal base that precisely aligns the arc focal point with the projector lens and cutoff shield. This produces a sharp beam cutoff, controlled light distribution, and reduced glare. Typical output ranges from ~3200–3500 lumens. - D2R HID Bulbs
Built specifically for reflector housings, D2R bulbs feature a partial opaque coating on the arc chamber to limit stray light and glare. They use a P32d-3 base, which is not interchangeable with D2S, ensuring housing-specific compatibility. Output is slightly lower (~2800–3200 lumens) due to glare-control shielding. - D2C HID Bulbs
A hybrid aftermarket variant marketed as a combined D2S/D2R solution. While D2C bulbs may physically fit both housings making them better suited for off-road or non-road use.
All D2 bulbs require a separate external igniter, unlike D1S or D3S bulbs with integrated igniters and use a projector and Reflector Housing. Electrical operation is regulated by a 35W HID ballast, supplying 85V AC during sustained operation after high-voltage ignition.
Products Included in This Collection
D2S Xenon HID Headlight Bulb Set (PAIR)
Designed for projector headlight housings, these D2S HID bulbs use a P32d-2 keyed base to align the xenon arc precisely with projector optics. Operating at 35W with an external igniter, they deliver ~3200–3500 lumens. Available in 6000K white and 8000K white/blue.
D2S 5000K Extreme White Xenon HID Bulbs (PAIR)
A visibility-focused upgrade producing a neutral 5000K white beam closer to daylight than OEM 4300K. Optimized for projector systems, these bulbs balance usable brightness, contrast, and beam clarity, making them suitable for daily night driving.
D2R Xenon HID Headlight Bulb Set (PAIR)
Engineered for reflector housings, D2R bulbs feature an opaque arc coating to reduce glare and control light scatter. Using a P32d-3 base, they are not interchangeable with D2S. Output is slightly reduced to maintain safe reflector performance.
D2H HID Replacement Bulbs – 3700 Lumens (PAIR)
Aftermarket conversion-focused HID bulbs delivering ~3700 lumens, intended for D2-style retrofit systems. Available in 6000K white and 8000K white/blue, these bulbs prioritize brightness but require proper housing and ballast pairing.
D2H HID CANbus Kit, 35W (PAIR)
A complete 35W HID conversion kit including D2H bulbs, ballasts, igniters, and CANbus circuitry. Designed for 12V vehicles, it prevents flickering and dashboard errors, making it suitable for modern ECU-monitored systems.
Available color temperatures include:
- 4300K (OEM warm white, highest usable brightness)
- 5000K (neutral white with improved contrast)
- 6000K (daylight white, most popular aftermarket option)
- 8000K (white with blue tint; aesthetic-focused)
D2 HID systems are commonly used in low-beam and bi-xenon projector applications, where beam control is handled by the housing optics, not the bulb. Correct housing matching (D2S → projector, D2R → reflector) is mandatory for DOT/ECE compliance, glare control, and safe road use.
