Car roof interior light with double tip decoding and reading functions, available as a metal license plate light in white, with LED light options for 31mm 18-light, 36mm 27-light, 39mm 30-light, and 41mm 33-light configurations for vehicle installation.
Car Roof Light with Double Tip Decoding and Multi-Size LED Options for Vehicle Interiors

This specialised automotive interior light serves a dual purpose, combining a roof light's general illumination with a specific decoding function facilitated by its double-tip design. It operates on the standard 12V DC power supply found in vehicles, with a modest 150mA current draw, ensuring compatibility without overloading the electrical system. The unit also performs as a reading light, adding to its cabin utility, and can be utilised as a license plate light. Available in a clean white finish, it is offered in four distinct configurations based on size and LED count, allowing for a tailored choice depending on the required brightness and fit.
Features and Construction

The product's core feature set is defined by its specific automotive functions and adjustable specifications. Its construction and available options are detailed in the following sections.
Material and Build
The light housing is constructed from aluminium, a material chosen for its favourable strength-to-weight ratio and resistance to corrosion, which is beneficial in the variable temperature and humidity environment of a vehicle interior. This material choice contributes to the product's durability without adding significant weight. The finish is listed as white, providing a neutral aesthetic that suits most car interior colour schemes. The build focuses on the functional integration of the LED array within this aluminium casing.
Size and Practical Fit
The product is not a single-sized item but is offered in four specific size configurations: 31mm, 36mm, 39mm, and 41mm. Each size corresponds directly to a different quantity of LED lights: 18, 27, 30, and 33 lights respectively. This range allows the buyer to select a unit based on the physical space available in their vehicle's roof console or other mounting location and the desired level of illumination, with the larger sizes typically offering more light output due to the higher LED count.
Uses and Placement

This light is designed for integration into a vehicle's interior lighting system, fulfilling several potential roles based on its stated functions and the user's needs.
Event or Professional Use
The primary differentiator is the 'decoding' function implied by the double-tip design. This suggests a use case beyond general illumination, potentially for tasks requiring focused, directed light on specific details, such as reading small print, maps, or diagnostic codes within the cabin. Its application as a reading light supports this, making it suitable for professional drivers, taxi operators, or enthusiasts who need clear task lighting without leaving the driver's seat.
Everyday Home Use
While designed for automotive use, the principles of its function translate to providing reliable cabin lighting for all drivers and passengers. It serves as a direct replacement or upgrade for a standard interior roof light, offering potentially brighter and more focused illumination for finding items in the car at night or for passenger reading during journeys. Its secondary function as a license plate light also adds to its overall vehicular utility.
Benefits and Buying Value

The value of this product lies in its multifunctional design and the ability to choose a specification that matches specific requirements.
Reuse and Low Maintenance
As a solid-state LED-based product housed in aluminium, it is designed for long-term use with minimal maintenance. LEDs are generally known for lower power consumption and longer lifespans compared to traditional bulbs, which, combined with the robust housing, suggests a product intended for durable service. The 12V DC operation ensures it is a direct fit for the vehicle's existing power infrastructure.
Why Choose This Product
This light stands out for its dedicated decoding and reading functions, a feature not commonly found in standard interior car lights. The choice between four size and light-output configurations (31mm/18-light, 36mm/27-light, 39mm/30-light, 41mm/33-light) provides flexibility. Buyers can select the exact model that fits their vehicle's physical constraints and lighting needs, moving away from a one-size-fits-all approach. The aluminium construction offers a practical balance of durability and weight.
