Lampada faretto Osram D1S Xenarc Original 35W 4200K (MPN 66140-1HB)

Osram D1S Xenarc Original 35W 4200K is a xenon HID headlight bulb intended for vehicles equipped with D1S discharge lamp fittings. The lamp produces a daylight-balanced light at approximately 4200 K and is engineered to match original equipment performance for precise beam geometry in xenon lighting systems. Designed for use where D1S bulbs are specified, it provides consistent luminous output for low- or high-beam applications in compatible headlamp units.

Advantages

The bulb offers stable light color and intensity that align with factory xenon systems, ensuring predictable beam pattern and glare control. With a 35W power rating it maintains vehicle electrical compatibility typical for HID installations. Manufactured according to automotive lighting standards, the lamp is intended to deliver a reliable replacement option that preserves the optical alignment and performance of xenon headlight modules.

Suitable for

• Replacement of D1S xenon bulbs in compatible headlamp assemblies
• Vehicles requiring daylight-balanced 4200 K light for improved visibility
• Applications demanding accurate beam pattern and minimal stray light

Key specifications

• Technology: Xenon high-intensity discharge (HID)
• Nominal power consumption: 35 W
• Color temperature: approximately 4200 K (daylight-balanced)
• Base/fitting type: D1S discharge lamp fitting
• Intended use: automotive low- and high-beam in compatible xenon headlamp units

How to use

To replace the bulb, disconnect the vehicle battery if recommended by the vehicle manufacturer, access the headlamp housing according to the vehicle service manual, and remove the existing D1S module or bulb assembly following safety precautions for high-voltage HID systems. Install the replacement bulb by handling only the base or protective housing—avoid touching the glass surface to prevent contamination that can affect light output. Reassemble the headlamp unit and check beam alignment and electrical connections per the vehicle specifications.

Recommendations

Handle HID bulbs with care and follow vehicle manufacturer guidelines for replacement and disposal. Do not touch the glass with bare hands; use gloves or a clean cloth. After installation, verify correct beam alignment to avoid dazzling other road users and ensure compliance with local road regulations.
