## Summary description

Automotive LED headlight bulb Amio AMI-02847 is a 4-side COB replacement for HB4 (P22d) halogen bulbs. It provides directional light from four chip-on-board surfaces for improved beam pattern and visibility. Designed for use in vehicle low- or high-beam housings compatible with HB4/P22d fittings, it suits everyday driving and night-time road illumination.

## Long description

Amio AMI-02847 is a halogen-replacement LED headlight bulb engineered as a direct-fit alternative for HB4 (P22d) sockets. The lamp uses four chip-on-board (COB) emitting surfaces arranged around the bulb body to create a directional light pattern intended to match reflector and projector housings designed for HB4 bulbs. The compact design and integrated cooling elements allow installation in many low- and high-beam applications where HB4/P22d fittings are used, improving nighttime road visibility while maintaining compatibility with standard automotive headlamp connectors.
Advantages
The four-side COB layout produces a controlled beam profile with reduced stray light and improved cut-off compared with single-sided LED designs, helping to optimise illumination of the roadway. The LED technology provides lower power consumption and longer operational life than halogen equivalents. The bulb’s standard HB4/P22d form factor ensures straightforward replacement without modifying the headlamp housing or connector in most vehicles.
Suitable for
Replacement of HB4 (P22d) halogen bulbs in compatible low-beam housings
Replacement of HB4 (P22d) halogen bulbs in compatible high-beam housings
Everyday urban and intercity driving
Night-time road illumination where a precise beam pattern is required
Key specifications
Fitting type: HB4 / P22d compatible base
Light source: 4-side chip-on-board (COB) LEDs
Intended use: automotive headlight, low-beam or high-beam applications
Power supply: vehicle 12 V electrical system (typical for automotive bulbs)
Cooling: integrated passive cooling design suitable for headlight housings
Color rendering and temperature: designed to produce a white driving light consistent with LED headlight outputs
How to use
Turn off the vehicle ignition and allow the headlight assembly to cool before replacing the bulb. Remove the headlamp access cover or dust cap, disconnect the existing HB4/P22d halogen bulb from its connector and carefully extract it from the reflector or projector housing. Insert the Amio AMI-02847 LED bulb into the same socket, ensuring the base is fully seated and the orientation aligns with the housing for optimal beam pattern. Reconnect the power connector, replace the access cover, and test the light function before driving.
Usage recommendations
Check local regulations regarding LED retrofits in headlamp reflectors or projectors and confirm compatibility with your vehicle’s headlight housing. After installation, verify beam alignment and adjust the headlamp aim if necessary to avoid glare to other road users. If the vehicle has a CAN-bus system or bulb monitoring, additional resistors or an error-cancelling adapter may be required to prevent dashboard warning messages.
