1. Introduction
This manual provides essential information for the safe and effective use of your OSRAM D1S Xenarc Original HID Xenon Bulb, model 66140. These bulbs are designed for automotive headlight applications, offering high intensity discharge (HID) lighting with OEM quality. Please read this manual thoroughly before installation and operation.
2. Safety Information
WARNING: HID xenon bulbs operate at extremely high voltages (up to 25,000V during ignition) and temperatures. Improper handling or installation can result in severe electrical shock, burns, or damage to the vehicle's electrical system.
- Always disconnect the vehicle's battery before attempting any installation or maintenance.
- Avoid touching the glass part of the bulb with bare hands. Oils from your skin can create hot spots and reduce bulb lifespan. Use clean gloves or a lint-free cloth.
- Do not operate the bulb outside of its intended housing or without proper ballast.
- Ensure the bulb is correctly seated and secured in the headlight assembly before reconnecting power.
- Dispose of old bulbs according to local regulations, as they contain mercury.
- It is highly recommended that installation be performed by a qualified automotive technician.

4. Installation (Setup)
Due to the high voltage involved and the complexity of modern vehicle headlight systems, professional installation by a certified mechanic is strongly recommended. Attempting self-installation without proper knowledge and tools can lead to injury or damage.
General Installation Steps (for reference only; consult vehicle-specific manual):
- Safety First: Ensure the vehicle is turned off, the ignition key is removed, and the battery's negative terminal is disconnected. Allow the headlight system to cool down.
- Access Headlight Assembly: Depending on the vehicle, this may involve removing covers, trim, or even the entire headlight unit.
- Remove Old Bulb: Carefully disconnect the electrical connector from the old HID bulb. Release any retaining clips or twist-lock mechanisms holding the bulb in place. Gently remove the old bulb without touching the glass.
- Install New Bulb: Wearing clean gloves, carefully insert the new OSRAM D1S bulb into the headlight housing. Ensure it is correctly oriented and fully seated. Secure it with the retaining clips or twist-lock mechanism.
- Connect Electricals: Reconnect the electrical connector to the new bulb. Ensure a secure connection.
- Test and Reassemble: Reconnect the vehicle battery. Turn on the headlights to verify proper operation. Once confirmed, reassemble any removed covers or trim.

5. Operation
The OSRAM D1S Xenarc bulb is a High-Intensity Discharge (HID) lamp. When activated, an electrical arc is created between two electrodes within a sealed glass chamber containing xenon gas and metal salts. This arc excites the gas, producing intense light. HID bulbs require a ballast (integrated into the D1S design) to provide the high voltage needed for ignition and to regulate the current during operation.
Upon initial activation, HID bulbs may take a few seconds to reach full brightness and color stability. This is normal operation and is known as "warm-up" time.

6. Maintenance
OSRAM D1S Xenarc bulbs are designed for long operational life and generally require minimal maintenance. However, proper care can help maximize their lifespan and performance:
- Avoid Frequent On/Off Cycles: Like all discharge lamps, frequent switching on and off can reduce the lifespan of HID bulbs.
- Keep Headlight Lenses Clean: Regularly clean your vehicle's headlight lenses to ensure maximum light output and prevent scattering.
- Inspect Wiring: Periodically check the wiring and connectors for any signs of wear, corrosion, or damage.
- Professional Inspection: Have your vehicle's lighting system inspected by a professional during routine maintenance.
