What It Is

The TecUpdater T10 W5W LED bulb is a 12V high-brightness replacement for standard halogen T10-type bulbs used in interior and auxiliary automotive lighting. Built using 26 pieces of 4014 SMD LEDs, it provides uniform illumination in a compact plug-and-play format.

It is compatible with common T10-type bases including:

• T10

• W5W

• 168

• 194

• 921

Available colour options:

• White

• Red

• Amber

• Blue

Supplied as a pair (2 bulbs).

What Problem It Solves

Most factory T10 halogen bulbs produce:

• Yellowish light output

• Uneven illumination

• Higher heat

• Short operating life

When vehicles are upgraded with LED headlights or DRLs, the interior and auxiliary halogen bulbs often look outdated and mismatched.

This LED upgrade provides:

• Brighter and cleaner light output

• Better reflector fill

• Reduced heat compared to halogen

• Lower power consumption

• Improved visual consistency with modern lighting

Additionally, many modern vehicles monitor bulb resistance and may trigger warning messages when standard LEDs are installed. These bulbs are designed with CANBUS-compatible circuitry to reduce dashboard errors and flickering in most vehicles.

In rare cases, depending on vehicle sensitivity, additional resistors may be required.

Light Output and Colour Options

Each bulb uses 26 high-output 4014 SMD LEDs arranged for multi-directional illumination. This layout helps minimise dark spots inside housings.

White (Approx. 6000K)
Commonly used for interior cabin lighting, license plate lights, glovebox lights, boot lights, parking lamps and map lights. Provides a clean, modern appearance.

Red
Suitable for rear position lighting, brake-related auxiliary use, and custom interior applications where red illumination is required.

Amber
Used for side markers, indicators, and positions where amber colour is mandatory.

Blue
Commonly used for custom interior lighting, footwell lighting, and styling applications where blue illumination is preferred.

Colour selection should always match the intended application and local lighting regulations.

CANBUS Compatibility

These bulbs are designed for high CANBUS compatibility to reduce:

• Bulb-out dashboard warnings

• Flickering behaviour

• Hyper-sensitive error messages

Compatibility depends on vehicle electronics. Most vehicles will not require additional resistors.

Universal Socket Compatibility

These bulbs fit standard T10-type sockets commonly found in vehicles from:

• Volkswagen

• Skoda

• Hyundai

• Kia

• Tata

• Mahindra

• Maruti Suzuki

• Honda

• Toyota

Application varies by model and year. Always verify bulb type before purchase.

Installation Notes

• Direct plug-and-play replacement

• No wiring modification required

• No coding required

• Polarity sensitive — rotate 180° if it does not illuminate

Who Should Buy This

• Users upgrading interior halogen lighting to LED

• Drivers replacing yellow parking or license plate bulbs

• DIY users seeking simple plug-and-play LED conversion

• Workshops performing quick lighting upgrades

Who Should Not Buy This

• Vehicles not using T10 / W5W base

• Applications requiring high-power external lighting

• Users installing incorrect colour for regulated lighting positions
