Set of Amio halogen headlight bulbs HB4 (P22d), 12V 51W LumiTec LIMITED +130% DUO BOX is designed as a direct-replacement lamp for vehicles that require HB4 bulbs. Each set contains two matching bulbs intended for low-beam or high-beam applications where HB4 compatibility and improved luminous output are needed. The LumiTec LIMITED filament and optimized envelope shape aim to deliver stronger forward illumination compared with standard 12V 51W halogen bulbs, while maintaining fitment and electrical compatibility for conventional halogen headlamp systems.
Advantages
The Amio HB4 LumiTec LIMITED bulbs provide up to 130% increased light output relative to typical reference halogen lamps of the same power, offering improved visibility at similar power consumption. The DUO BOX packaging supplies a matched pair to ensure even light colour and intensity between left and right headlamps. Designed for simple replacement, these bulbs retain the standard HB4 base and electrical characteristics, reducing installation complexity and preserving existing headlamp beam pattern when installed correctly.

How to use
Turn off the vehicle ignition and headlamp switch before replacing bulbs. Access the headlamp housing according to the vehicle manufacturer’s instructions, remove the protective cap or connector, and carefully disconnect the bulb electrical connector. Remove the old HB4 bulb by releasing its retaining mechanism, then install the new Amio HB4 bulb by aligning the base, securing it in place, and reconnecting the electrical plug. Avoid touching the glass envelope with bare fingers; if contact occurs, clean with isopropyl alcohol and a lint-free cloth. After installation, check headlamp alignment and beam pattern and test both low-beam and high-beam functions to ensure proper operation.
Usage recommendations
Use these bulbs in headlamp housings designed for HB4 (P22d) lamps and within compatible electrical systems. Do not exceed vehicle manufacturer guidelines for bulb types and beam alignment. For optimal and legal performance, have headlamp aim checked after installation and replace bulbs as matched pairs to maintain uniform light colour and intensity.
