LED car bulb BA9S BAX9S 4 SMD 5050 CAN BUS

The BA9S LED car bulb with 4 SMD 5050 diodes is the perfect solution for drivers looking for bright and reliable LED lighting. Thanks to the built-in CAN BUS system, the bulb does not cause errors on the dashboard, making it ideal for modern cars. The standard BA9S socket type allows easy installation in most vehicles.

Main advantages:

• Bright light: 4 SMD 5050 diodes provide strong and uniform lighting.
• CAN BUS system: Eliminates errors on the dashboard.
• Easy assembly: Standard socket type BA9S/T4W.
• Energy efficiency: LED technology reduces energy consumption.
• Long service life: Minimizes the need to replace a bulb.

SMD 5050 diodes - Power and efficiency:

SMD 5050 diodes are a technologically advanced LED light source, characterized by high power and efficiency. Each 5050 diode contains three LED chips, which allows for a brighter light compared to smaller SMD diodes. This makes 5050 diode bulbs ideal for applications where strong and intensive lighting is required.

Technical specifications:

• Mounting type: T4W (BA9S) / H6M (BAX9S) - to choose from
• Number of LEDs:
• LED type:
• Supply voltage: 12V
• Light color: cold white
• Polarization: not neutral. If the bulb does not light up after installation, reverse the polarity in the socket.
• Replacement bulbs: T4W, BA9S

Bulb size:

• Length: 38mm
• Width: 12mm

Difference between BA9S and BAX9S (T4W and H6W):

• BA9S (T4W):

  Socket with symmetrical pins in the shaft.

  Mainly used in interior lighting, license plate lighting and position lights.

• BAX9S (H6W):

  Socket with asymmetrical pins in the shaft.

  Mainly used in position lights and daytime running lights.

The difference in the pin arrangement prevents these types of bulbs from being interchangeable.

To eliminate the possibility of confusion, please check which bulbs are currently installed in your car before purchasing.

T4W BA9S LED bulbs are most often used as a lighting source in:

• parking lights (front)
• vehicle interior lighting, including "for reading"
• luggage area illumination
• middle light "STOP"
• yacht lighting, for camper

We recommend purchasing bulbs marked with the CANBUS symbol if the car is equipped with a bulb efficiency check system. Errors on the on-board computer most often concern the use of inappropriate T4W LED bulbs in the license plate light. In addition, light bulbs CAN-BUS works with the dimming module light bulbs in the interior. A standard LED bulb will operate in binary mode, meaning it will emit 0% or 100% light.
