Product Information
Full details
The Osram Original Line R2 (64183) is designed for drivers seeking a dependable, OEM-quality lighting solution for older or classic vehicle headlamp systems. Delivering a warm 3200K color temperature and a robust 45/40W output, this bulb provides reliable illumination and essential road visibility; however, as a traditional halogen bulb, it lacks the intense white light profile and energy efficiency found in modern LED or HID retrofits.

FAQs
Does this bulb work on 24V systems?
No, this is a 12V bulb intended for standard passenger vehicles. Using it on a 24V system will cause immediate failure.
Can I touch the glass during installation?
It is highly recommended not to touch the glass. Oils from your hands can create hot spots on the halogen quartz glass, leading to premature burnout.
How do I know if this fits my car?
Consult your vehicle's owner's manual or check the markings on your existing bulb to confirm it requires a P45t base and R2 sizing.
Is this a street-legal bulb?
Yes, this is a standard-wattage automotive replacement bulb designed to comply with general road safety lighting regulations.
Why is the light yellow compared to newer cars?
The 3200K color temperature produces a warm, traditional halogen glow, whereas newer vehicles often use HID or LED sources that operate at 5000K-6000K for a blue-white appearance.
Troubleshooting
Bulb fails to illuminate after installation
Check the fuse box for a blown headlight fuse and verify that the electrical connector is fully seated on the bulb base.
Bulb dimmed shortly after installation
Verify that no skin oils are present on the glass. If touched, clean the bulb with isopropyl alcohol and a clean lint-free cloth.
Flickering light
Inspect the headlight wiring harness for signs of corrosion or loose grounding points common in older vehicle systems.

Setup, Compatibility & Care
Installation:
- Ensure the vehicle is powered off and the headlight switch is in the 'OFF' position.
- Access the rear of the headlight assembly by removing the protective dust cap.
- Disconnect the electrical connector from the base of the old bulb.
- Carefully unclip the wire retainer or twist-lock mechanism to remove the old bulb.
- Insert the new Osram 64183 bulb, ensuring it is seated firmly in the P45t socket.
- Crucial: Avoid touching the glass portion of the new bulb with bare fingers; oils from your skin can cause the bulb to overheat and fail prematurely. Use a clean cloth or glove.
Compatibility:
This bulb is specifically designed for 12V automotive systems using the R2 bulb size and P45t base. Always check your vehicle owner's manual to verify the specific bulb type required for your headlight housing before purchase.
