OSRAM 64151ALS Bulb Cornering Lamp

OSRAM 64151ALS Bulb Cornering Lamp

The OSRAM 64151ALS is a high‑performance H3 halogen cornering lamp designed to deliver exceptional illumination for both automotive and motorcycle applications. With its robust construction, precise beam pattern, and versatile compatibility, this bulb is the preferred choice for drivers who demand reliable visibility on winding roads, night driving, and challenging weather conditions.

Key Technical Specifications

• Type: H3 halogen lamp (also referred to as a “spotlight” or “cornering light”)
• Power Rating: 55 W
• Voltage: 12 V DC
• Luminous Flux: Approximately 3,200 lumens (typical for H3)
• Color Temperature: 3,200 K (warm white)
• Beam Pattern: Focused spot with a long‑range reach; ideal for high‑speed cornering and off‑road use
• Base Type: E12.5 (standard H3 socket)
• Operating Temperature Range: –40 °C to +70 °C (suitable for extreme climates)
• Lifetime: Up to 1,000 hours under normal operating conditions

Design & Construction

The bulb features a durable glass envelope that protects the halogen gas and tungsten filament from moisture, vibration, and temperature fluctuations. The sealed‑gas technology ensures consistent performance over its lifespan, while the high‑quality reflector focuses light into a precise beam pattern. The compact size of the H3 design allows it to fit seamlessly into a wide range of vehicle lighting assemblies.

Compatibility & Vehicle Applications

The OSRAM 64151ALS is engineered for universal use across many popular car and motorcycle models. Below are some of the most common applications:

• Automotive: Volkswagen, Audi, Mercedes‑Benz, BMW, Ford, Fiat, Mitsubishi, Hyundai, Honda, Nissan, Toyota, Subaru, Mazda, Kia, Hyundai, and many others.
• Motorcycles & Scooters: Yamaha, Vespa, Vauxhall, UAZ, Alfa Romeo, Aprilia, Ducati, Harley‑Davidson, and more.
• Specialty Vehicles: Off‑road trucks, SUVs, and commercial vehicles that require high‑intensity cornering lights.

Because the bulb uses a standard H3 base, it can be swapped into any vehicle equipped with an H3 socket without modification. This makes it an ideal replacement for aging or damaged lamps in both new and older models.

Installation Guide

1. Safety First: Disconnect the battery to prevent accidental short circuits.
2. Remove Old Lamp: Open the headlamp assembly, locate the H3 socket, and gently twist or pull out the old bulb. Avoid touching the glass envelope with bare hands; use gloves or a cloth if necessary.
3. Insert New Bulb: Align the base of the OSRAM 64151ALS with the socket and insert it until it clicks into place. Ensure that the bulb is seated firmly to avoid vibration damage.
4. Reassemble Headlamp: Close the assembly, secure any screws or clips, and reconnect the battery.
5. Test Functionality: Turn on the vehicle’s lighting system to verify that the new bulb illuminates correctly. Check for proper beam alignment and intensity.

Performance Highlights

• High Brightness: The 55 W rating delivers a powerful, focused beam that extends visibility up to 200–250 meters on clear roads.
• Consistent Beam Pattern: Designed to maintain its shape and intensity throughout the bulb’s life, ensuring reliable cornering performance.
• Low Heat Emission: The halogen design keeps heat levels manageable, reducing the risk of damage to surrounding components.
• Energy Efficiency: While delivering high output, the bulb consumes only 55 W—an optimal balance between brightness and power draw for modern vehicles.

Durability & Reliability

The OSRAM 64151ALS is built to withstand harsh driving conditions. Its sealed‑gas construction resists moisture ingress, while the robust glass envelope protects against vibration and impact. The bulb’s long lifespan—up to 1,000 hours—means fewer replacements and lower maintenance costs over time.

Safety & Environmental Considerations

• Halogen Gas: The bulb contains a small amount of halogen gas that reacts with the tungsten filament to maintain brightness. Proper handling is essential; avoid crushing or puncturing the glass.
• Recycling: At end‑of‑life, dispose of the bulb in accordance with local regulations for electronic waste. Many municipalities accept halogen bulbs in designated recycling programs.
• Eye Protection: When inspecting or replacing the bulb, wear safety glasses to protect against accidental splashes of hot glass or filament fragments.
