With its compact size and reliable brightness, it delivers clear visual signals for turn indicators, brake lights, reverse lamps, and other auxiliary lighting systems in vehicles ranging from cars to motorcycles and light trucks.

Key Technical Specifications

• Model: PY21W (also known as 7507)
• Voltage: 12 V DC
• Power Consumption: 21 W
• Base Type: BAU15s with offset pins for secure mounting
• Luminous Intensity: Approximately 1,200 lumens (typical for halogen indicator lamps)
• Color Temperature: Amber/Yellow (standard automotive signaling color)
• Operating Life: Up to 2,000 hours under normal driving conditions
• Dimensions: Standard halogen bulb size suitable for most vehicle indicator housings
• Certification: Meets automotive safety standards (e.g., ISO 2133, SAE J1105)

Design Features and Construction

The OSRAM 7507 employs a robust metal base that ensures excellent electrical contact and heat dissipation. The offset pin arrangement allows for precise alignment within indicator housings, reducing the risk of misfit or loose connections. Its halogen glass envelope is engineered to withstand the high temperatures generated during operation while maintaining optical clarity.

Applications Across Vehicle Types

This bulb is versatile and widely used in:

• Passenger cars (e.g., Audi, BMW, Mercedes‑Benz, Volkswagen)
• Light trucks and SUVs (e.g., Ford, Chevrolet, Toyota)
• Motorcycles and scooters (e.g., Suzuki, Yamaha)
• Commercial vehicles such as vans and delivery trucks
• Specialized automotive systems like reverse lamps, brake lights, and turn signal indicators

Installation and Compatibility

The bulb’s BAU15s base is compatible with a wide range of indicator housings that accept the standard 15 mm offset pin configuration. Installation typically involves removing the existing lamp, aligning the offset pins with the housing contacts, and securing it in place. Because the OSRAM 7507 is designed for automotive use, it can be directly swapped into most vehicles without requiring additional adapters or modifications.

Performance and Reliability

OSRAM’s commitment to quality engineering ensures that each 7507 bulb delivers consistent brightness throughout its lifespan. The halogen technology provides a bright amber glow that is easily visible in daylight, dusk, and nighttime conditions. Its high power rating (21 W) guarantees sufficient illumination for safety-critical signaling functions.

Environmental Considerations

The bulb’s halogen composition is fully recyclable under automotive recycling programs. OSRAM emphasizes the use of materials that comply with environmental regulations, ensuring minimal ecological impact during disposal or end‑of‑life processing.

Maintenance and Replacement Tips

• Inspect bulbs regularly for signs of discoloration or dimming; replace if performance drops below expected levels.
• Avoid touching the glass surface with bare hands to prevent oil residue that can accelerate degradation.
• When replacing, ensure the vehicle’s electrical system is turned off and disconnect the battery to avoid short circuits.

Conclusion

The OSRAM 7507 Light Bulb stands out as a reliable, high‑quality solution for automotive lighting needs. Its precise engineering, durable construction, and proven performance make it an ideal choice for anyone seeking to maintain or upgrade vehicle indicator systems with confidence.
