Product Specifications

This 12V 55W H1 Extreme Life halogen headlight bulb with P14.5s base is a high-durability automotive lighting product designed for reliable long-term use. It adopts the standardized P14.5s single-contact base, ensuring excellent compatibility with most original H1 headlight assemblies. Users can complete replacement directly without circuit modification, making it an ideal OEM-equivalent upgrade for passenger cars, commercial vehicles and other 12V automotive lighting systems.

Built for extended lifespan, the bulb uses high-purity quartz glass and reinforced tungsten filament, filled with high-pressure inert gas to slow down filament attenuation and enhance resistance to vibration and high temperature. Its service life reaches more than 450 hours, greatly exceeding that of standard halogen bulbs, effectively reducing frequent replacement and maintenance costs. With a rated voltage of 12V and power of 55W, it maintains stable output under vehicle electrical system fluctuations, avoiding overload or abnormal heat generation, thus improving driving safety and stability.

In terms of illumination performance, the bulb delivers a luminous flux of approximately 1550lm and a color temperature between 3200K and 3450K, providing natural warm white light with strong penetration. It maintains clear visibility in rainy, foggy and snowy conditions, effectively illuminating road conditions and traffic signs. The anti-UV quartz tube prevents lamp housing yellowing and aging, preserving long-term light transmittance.

Compliant with ECE R37 international regulations, the bulb features a standard light pattern without glare, ensuring no interference to oncoming vehicles. Combining durability, safety and stable lighting, this H1 Extreme Life halogen bulb is a professional and cost-effective solution for automotive lighting replacement and upgrade, suitable for both daily commuting and long-distance driving scenarios.
