Amio 1156 LED CANbus 24 SMD 3030 T20 (7440/W21W) amber 12V/24V bulb

Amio 1156 LED CANbus 24 SMD 3030 T20 (7440/W21W) amber 12V/24V bulb is a compact automotive signal lamp designed to replace conventional single-contact bulbs in 12V and 24V electrical systems. It features 24 SMD 3030 LED chips arranged to provide even amber illumination with a T20 (1156/7440/W21W) base, and includes CANbus compatibility to prevent error messages on modern vehicle electronics. The bulb is intended for use in turn signals, side marker lights and other indicator applications where reliable, error-free operation and a direct fit are required.

Advantages

This Amio LED bulb delivers consistent amber light output with low power consumption compared to incandescent equivalents, while its CANbus compatibility reduces the likelihood of dashboard warning indicators on vehicles with monitoring systems. The compact T20 form factor ensures direct replacement without modification in most fittings designed for 1156/7440/W21W bulbs. The use of 24 SMD 3030 chips provides broad light dispersion and stable color temperature suitable for signaling purposes.

Suitable for

• Turn signals (front and rear)
• Side marker lights
• Brake/parking light circuits that accept single-contact T20/1156 style bulbs
• Vehicles with CANbus systems that require error-free LED replacements

Key specifications

• LED type: 24 × SMD 3030
• Color: amber
• Base/type: T20 (compatible with 1156/7440/W21W fittings)
• Operating voltage: 12 V and 24 V
• CANbus: compatible (designed to reduce error signals on monitored circuits)
• Application: automotive signal and indicator lighting

How to use

Ensure the vehicle electrical system voltage matches the bulb specification (12V or 24V). Switch off the vehicle ignition and remove the existing 1156/7440/W21W bulb from its socket. Insert the Amio LED bulb into the T20 receptacle, ensuring correct seating for a secure mechanical and electrical connection. After installation, switch on the relevant lights and verify correct operation of turn signals, side markers or parking lights. If the vehicle displays a warning or rapid flash rate, consult the vehicle manual or a technician about load resistors or programming adjustments, although the CANbus compatibility is intended to prevent such issues.

Usage recommendations

For best results, replace bulbs in pairs on the same axle to maintain uniform light output and flash rate. Avoid touching the LED surface with bare hands during installation to keep the optics clean. If persistent warning signals occur after installation, verify socket condition and grounding before adding external resistors or adapters.
