OLM Alpha HD H11 5500K LED Bulbs | 4000 Lumens Output | High-Performance LED Replacement Bulbs

Overview

The OLM Alpha HD H11 5500K LED Bulbs are designed as a direct replacement for H16 and H11 low beam and fog light bulbs, delivering a significant upgrade in brightness and clarity for Subaru owners. These bulbs are ideal for drivers seeking improved road illumination with a crisp, white light output that enhances visibility beyond the limited reach of factory halogen bulbs. Crosstrek models equipped with steering responsive fog lights (SRF) are compatible with these bulbs, making them a versatile lighting upgrade across multiple Subaru platforms.

Engineered with a compact all-in-one design, the Alpha HD series utilizes efficient LEDs to maximize light output while maintaining an affordable price point. The adjustable base allows fine-tuning of the focal length to optimize beam pattern and intensity, ensuring the best possible lighting performance for your specific application. Additionally, the reversible heat sink design accommodates different housing profiles, providing a precise fit without compromising cooling efficiency or bulb longevity.

Unlike typical LED replacements that may look bright but fail to deliver usable light on the road, these bulbs produce between 3520 and 4000 lumens per pair, significantly outshining the factory 19W halogen bulbs that emit an orange light with limited reach. This upgrade not only improves driver awareness and safety during normal driving conditions but also enhances the overall Subaru ownership experience by providing reliable, high-quality lighting that performs well in various environments.
