Bosch D3S Xenon HID Headlight Bulb – 35W PK32d-5

The Bosch D3S Xenon HID headlight bulb is a high‑performance illumination solution designed for modern vehicles that demand superior visibility and aesthetic appeal. With its advanced xenon gas discharge technology, this bulb delivers an exceptionally bright, white light that closely mimics natural daylight, enhancing both safety and driving experience.

Key Technical Specifications

• Model: PK32d-5 (D3S series)
• Power Consumption: 35 W
• Voltage: 42 V DC
• Luminous Flux: Approximately 2,500–3,000 lumens (varies by manufacturer)
• Color Temperature: 4,200 K – a crisp, daylight‑like hue
• Beam Pattern: Long‑range projector with a focused beam for extended visibility
• Lifetime: Up to 3,000 hours under optimal conditions
• Compatibility: Designed for use in vehicles such as Audi, Volkswagen, Mercedes‑Benz, and many others that support the D3S xenon HID system

Design & Construction

The bulb features a robust, sealed housing that protects the internal components from vibration, temperature extremes, and moisture. Inside, a xenon gas discharge tube is surrounded by a phosphor coating that converts ultraviolet light into visible white light. The integrated reflector ensures precise beam shaping, directing illumination where it is most needed while minimizing glare for oncoming traffic.

Installation & Compatibility

Installing the Bosch D3S Xenon HID headlight bulb is straightforward for users familiar with automotive lighting systems. The bulb fits into standard PK32d-5 sockets and requires a 42 V power supply, typically provided by the vehicle’s headlamp control module. For vehicles originally equipped with halogen or low‑pressure sodium lamps, an appropriate HID conversion kit is necessary to accommodate the higher voltage and ensure proper operation.

Performance Benefits

• Enhanced Visibility: The high luminous flux and daylight color temperature provide clearer road perception, especially in adverse weather conditions.
• Reduced Glare: Precise beam shaping limits light spillover, protecting oncoming drivers while maintaining a wide illumination area.
• Energy Efficiency: At 35 W, the bulb offers a good balance between brightness and power consumption, extending battery life compared to higher‑power alternatives.
• Aesthetic Appeal: The bright white light complements modern vehicle styling, giving headlights a sharp, contemporary look.

Maintenance & Longevity

Regular inspection of the bulb’s housing and reflector is recommended to ensure optimal performance. While the bulb can last up to 3,000 hours, factors such as driving habits, environmental conditions, and electrical system quality may influence actual lifespan. When replacement is necessary, selecting a genuine Bosch D3S model guarantees consistent quality and reliability.

Applications Across Vehicle Brands

The D3S Xenon HID headlight bulb is engineered to fit a wide range of vehicles that support the PK32d-5 socket. Common applications include:

• Audi models: A3, A4, Q5, Q7, and others featuring long‑range projector systems.
• Volkswagen models: Passat, Golf, Tiguan, and various station wagons with xenon HID setups.
• Mercedes‑Benz vehicles: C‑Class, E‑Class, S‑Class, and other luxury lines that employ the D3S series for high‑performance lighting.
