## Summary description

Universal W21W T20 W3x16d automotive bulb with Canbus 24 compatibility, equipped with 24 SMD 3030 LEDs and designed for 12V/24V systems. Provides white light for signaling and marker applications, fits sockets using the W3x16d base. Suitable for cars and commercial vehicles requiring Canbus error-free replacement bulbs.

## Long description

Universal W21W T20 W3x16d Canbus 24 bulb with 24 SMD 3030 LEDs is designed for signaling and marker applications in 12V and 24V vehicles. The white light output provides clear, neutral illumination for indicators, side markers, position lamps and other sockets that accept the W3x16d base. The Canbus 24 compatibility ensures built-in resistance to common error messages on vehicle CAN bus systems, enabling direct replacement of conventional bulbs without triggering dashboard warnings on many modern cars and commercial vehicles.
Advantages
This LED replacement offers low power consumption compared with incandescent bulbs, extended service life and more consistent light output. The compact T20 form and W3x16d base provide straightforward mechanical compatibility with standard sockets. The 24 SMD 3030 diodes deliver uniform white light suitable for signaling, while Canbus 24 support reduces the risk of error codes or hyperflashing on compatible systems.
Suitable for
Indicator lights and turn signals
Side marker and position lamps
Brake/parking lamp applications that accept W21W/T20 bulbs
Passenger cars, vans and commercial vehicles with 12V or 24V electrical systems
Key specifications
LED type: 24 SMD 3030
Light color: white
Base type: W3x16d (T20/W21W form factor)
Operating voltage: compatible with 12V and 24V systems

How to use
Install the bulb into a matching W3x16d socket after switching off vehicle power and allowing existing lamps to cool. Press the bulb into the socket and rotate if required to achieve secure contact. Verify correct fit and lighting operation by switching on the relevant circuit (indicator, marker, or parking lamp). If a warning appears on the vehicle dashboard, check the vehicle manual and ensure the bulb is fully seated; in some systems additional load resistors or adapters may be required for full compatibility.
Usage recommendations
Use the bulb in dry, properly sealed lamp housings to avoid moisture exposure. For vehicles with advanced CAN bus diagnostics, confirm Canbus compatibility with the vehicle make and model before purchase. Replace bulbs in pairs for balanced appearance and consistent signaling performance.
