Car LED bulb Amio H1 4-side COB — single-beam headlight replacement

The Amio H1 4-side COB LED bulb is a compact replacement designed for H1 single-beam headlight sockets. It uses chip-on-board (COB) emitters arranged on four sides to produce a more uniform beam pattern compared with single-emitter LED conversions. The bulb is intended to replace halogen H1 lamps and deliver whiter, brighter illumination to improve visibility while maintaining the correct form factor for H1 fittings.

Advantages

The four-sided COB layout yields a wider and more even light distribution that helps reduce dark spots and uneven illumination on the road. Its compact construction fits into standard H1 housings without significant modifications. The LED technology offers lower power consumption and a longer expected life than traditional halogen bulbs, while producing a whiter light colour that enhances contrast and driver perception.

Suitable for

• Direct replacement of H1 single-beam halogen headlight lamps
• Drivers seeking improved forward illumination and whiter light
• Vehicles with compatible H1 sockets and adequate headlight housing clearance
• Daytime running or low/high beam applications where H1 is specified

Key specifications

• Bulb type: H1 form factor for single-beam headlight fittings
• LED arrangement: 4-side chip-on-board (COB) emitters for uniform beam
• Light colour: cool white/white (LED typical tone for improved contrast)
• Power and luminous output: LED characteristic offering reduced power draw compared with halogen (refer to vehicle electrical compatibility)
• Fitment: compact design to suit standard H1 housings without major modifications

How to use

Ensure the vehicle ignition is off and the headlight circuit is cool before beginning. Remove the existing H1 halogen bulb following the vehicle manufacturer’s instructions, taking care not to touch the LED surface with bare hands. Insert the Amio H1 4-side COB LED bulb into the H1 socket, secure the bulb according to the headlight assembly design, and reconnect any locking clips or covers. After installation, power on the headlights to check beam alignment and correct operation. If required, adjust the headlight aim to comply with local regulations and to ensure proper beam pattern on the road.

Usage recommendations

Verify compatibility with your vehicle’s electrical system and headlight housing before purchase. Some vehicles may require additional adapters, anti-flicker resistors, or LED drivers to prevent warning messages, flicker, or CAN-bus errors. Confirm local road regulations regarding LED replacements for halogen bulbs to ensure legal compliance.
