T10 LED Bulb COB Silicone High-power 12V DC Car Light 180 Degree 21.5mm x 9.5mm for Side Marker License Plate Door Trunk Reading Light White Red Blue Yellow Green Ice Blue Pink Purple
T10 COB LED Bulb 12V DC – 180-Degree High-Power Car Light in Silicone Body (10-Pack)

Replacing standard incandescent or weak LED bulbs in your car's auxiliary lighting can make a noticeable difference to visibility and safety. These T10 COB LED bulbs use a high-power chipset and a full 180-degree illumination angle to spread light more evenly through side markers, license plate lamps, reading lights, door lights, trunk lights, and roof lights. The silicone body absorbs vibration and dissipates heat, extending the bulb's usable life in demanding automotive environments. Each bulb runs on standard 12V DC, matching the typical output voltage of a car's electrical system, so no extra converters or modifications are needed. Available in a range of eight colours, these bulbs are supplied in a pack of ten, making them suitable for multiple applications in one vehicle or across several vehicles.
Features and Construction

Built around a COB (Chip-on-Board) LED array, these bulbs deliver consistent, bright light without the dark spots common with older SMD designs. The outer silicone sheath protects against moisture, dust, and vibration, while the compact form factor fits existing T10 wedge sockets.
Material and Build
The bulb body is made from flexible silicone, offering resistance to the vibration and heat found in automotive lighting compartments. The COB LED chip provides a high-density light source that emits a uniform beam across a 180-degree arc. The base is a standard T10 wedge with a 9.5mm offset socket.
Size and Practical Fit
Each bulb measures just 21.5mm in length and 9.5mm in diameter, with the offset socket matching standard T10 wedge holders found in many vehicles. The compact size allows installation in tight spaces such as door light housings or license plate light fittings without modification.
Uses and Placement

Because these bulbs operate on wide-angle 180-degree output, they suit both interior and exterior auxiliary lighting tasks. The ten-bulb pack provides enough units to upgrade multiple light points at once.
Event or Professional Use
For automotive workshops or hobbyists, these bulbs offer a quick upgrade for side marker lights, side turn signals, and trunk lights. The wide beam angle ensures the light is visible from the side and rear, improving safety during roadside stops or loading.
Everyday Home Use
Beyond the car, these 12V DC bulbs can power reading lights in campervans, boats, or caravans where low-voltage lighting is standard. The silicone body is less prone to shattering if dropped, making it a practical choice for mobile installations.
Benefits and Buying Value

Getting a set of ten bulbs at once reduces the per-unit cost and ensures you have spares for future replacements. The COB LED design uses less power than incandescent bulbs while providing brighter output, which can slightly reduce the load on your vehicle's electrical system over time.
Reuse and Low Maintenance
LED bulbs typically last longer than filament bulbs, but exact lifespan figures are not provided. The silicone body helps the bulb withstand the constant vibration of a moving vehicle, potentially reducing the frequency of replacements. Simply swap in a new bulb from the pack when needed.
Why Choose This Product
These bulbs offer a practical, no-fuss upgrade for standard T10 wedge-based fittings. The 180-degree beam covers a wider area, the eight colour options allow customisation, and the ten-bulb pack provides good value for multiple applications.
