1. Introduction
The OSRAM NIGHT BREAKER LASER H4 is a high-performance halogen headlamp designed for passenger cars. This bulb provides enhanced brightness and improved visibility for safer driving. This manual provides essential information for the safe installation, operation, and maintenance of your OSRAM NIGHT BREAKER LASER H4 headlamps.
2. Safety Information
- Always disconnect the vehicle's battery before attempting any electrical work, including bulb replacement.
- Allow bulbs to cool down completely before handling. Halogen bulbs operate at high temperatures.
- Avoid touching the glass part of the bulb with bare hands. Oils from your skin can create hot spots, leading to premature bulb failure. Use clean gloves or a lint-free cloth when handling.
- Ensure the new bulb is correctly seated and secured in the headlight assembly to prevent improper beam patterns or damage.
- Dispose of old bulbs responsibly according to local regulations.
- If unsure about the installation process, consult a qualified automotive technician or your vehicle's service manual.
3. Setup and Installation
Replacing an H4 halogen headlamp typically involves a few steps. Refer to your vehicle's owner's manual for specific instructions and access points for your headlight assembly.
- Prepare the Vehicle: Park the vehicle on a level surface, turn off the engine, and engage the parking brake. Open the hood.
- Disconnect Battery: For safety, disconnect the negative terminal of the vehicle's battery.
- Access Headlight Assembly: Locate the back of the headlight assembly. You may need to remove a cover or other components to gain access to the bulb.
- Disconnect Wiring Harness: Carefully unplug the electrical connector from the back of the old bulb.
- Remove Old Bulb: Release the retaining clip or spring that holds the bulb in place. Gently pull the old bulb straight out from its socket.
- Install New Bulb: Holding the new OSRAM NIGHT BREAKER LASER H4 bulb by its base (using gloves or a cloth), insert it into the headlight socket. Ensure the tabs on the bulb base align with the grooves in the socket.
- Secure Bulb: Re-engage the retaining clip or spring to firmly hold the new bulb in place.
- Reconnect Wiring: Plug the electrical connector back onto the terminals of the new bulb.
- Test and Reassemble: Reconnect the vehicle's battery. Turn on the headlights to ensure the new bulb is functioning correctly. Check both low and high beams. If necessary, adjust headlight aim according to your vehicle's specifications. Reassemble any covers or components removed earlier.

4. Operating Instructions
Once installed, the OSRAM NIGHT BREAKER LASER H4 headlamps operate like standard halogen bulbs. They provide both low beam and high beam functionality, controlled by your vehicle's existing headlight switch. These bulbs are designed to offer increased brightness and a longer light beam compared to standard halogen bulbs, enhancing visibility during night driving and in adverse weather conditions.

5. Maintenance
- Regular Inspection: Periodically check your headlights for proper function (both low and high beams).
- Clean Headlight Lenses: Keep your vehicle's headlight lenses clean from dirt, grime, and ice to ensure maximum light output.
- Bulb Lifespan: High-performance halogen bulbs, like the NIGHT BREAKER LASER, are designed for increased light output, which can sometimes result in a shorter lifespan compared to standard halogen bulbs. Consider replacing both bulbs at the same time if one fails to maintain consistent light output and color.
- Avoid Contamination: As mentioned in safety, avoid touching the glass of the bulb. If the bulb glass is accidentally touched, clean it with an alcohol wipe and allow it to dry before installation.
6. Troubleshooting
| Problem | Possible Cause | Solution |
