Why This 3156 LED Bulb Exists

Factory halogen 3156 bulbs typically produce a dull yellow output with slower illumination response. In reverse lights and turn indicators especially, delayed activation and weak brightness reduce visibility in modern traffic conditions.

The TecUpdater 3156 single-intensity LED bulb is engineered to deliver:

• Brighter and clearer illumination

• Instant LED response

• Reduced power consumption

• Cleaner, modern appearance

This bulb is designed specifically for single-function applications and is not intended for dual tail + brake use.

Single Intensity Function Explained

This 3156 bulb operates in one brightness mode only.

Suitable for:

• Reverse lights (White version)

• Turn indicators (Amber version)

• Parking lights

• Side markers

• Single-function tail lamp positions

It is not compatible with vehicles that require dual-intensity operation (tail + brake in one bulb such as 3157).

Always confirm your original bulb specification before ordering.

High Output 3030 LED Performance

Equipped with high-efficiency 3030 SMD LED chips, this bulb delivers:

• Uniform light distribution

• Better reflector utilization

• Instant illumination (no filament delay)

• Clean and sharp LED colour output

The design minimizes dark spots and ensures stable, evenly spread brightness inside the housing.

CANBUS-Compatible Design

Modern vehicles monitor bulb resistance and may trigger warnings when installing standard LEDs.

This TecUpdater 3156 LED bulb includes integrated CANBUS-compatible circuitry to help reduce:

• Dashboard bulb-out errors

• Flickering issues

• Voltage fluctuation effects

In most vehicles, additional load resistors are not required. However, sensitivity varies by model.

Housing Options

Available in:

• Black body – stealth appearance, ideal for darker housings

• White body – traditional reflective styling

Lighting performance remains identical in both versions.

Interchangeable Base Compatibility

Physically compatible with the following wedge-base family:

• 3156

• 3056

• 3456

• 4156

• 5702

This is a single-intensity configuration only.

Do not use in dual-filament applications like 3157 tail + brake combinations.

Installation Guidelines

1. Switch off ignition.

2. Access the lamp housing.

3. Remove the existing halogen bulb.

4. Insert the LED bulb securely into the socket.

5. Test before closing the housing.

If the bulb does not illuminate, rotate 180° (polarity sensitive design).

Professional installation is recommended where access is restricted.

Common India Market Applications

Commonly used in select variants of:

Volkswagen – Polo, Vento, Ameo
Skoda – Rapid, Octavia
Hyundai – Verna, Creta, i20
Honda – City, Jazz
Toyota – Corolla Altis, Innova

Fitment varies by year and variant. Always confirm original bulb type before purchase.

Key Benefits

• Brighter output compared to halogen

• Instant LED response time

• Lower power consumption

• Modern, clean lighting appearance

• Reduced error occurrence in most vehicles

FAQs

Can this replace a 3157 bulb?
Only if your application requires single-intensity. It will not support dual brightness.

Will this cause hyper-flash?
Some vehicles may still require an external resistor depending on wiring sensitivity.

Is it suitable for brake + tail combination?
No. This is a single-intensity 3156 bulb only.
