Car roof light in a double tip decoding reading metal design with aluminium construction and 31mm, 36mm, 39mm, or 41mm sizes available in white, featuring a 12V DC power requirement and 150ma current for precise interior illumination.
Aluminium Double Tip Car Roof Light in Four Sizes for Custom Interior Illumination

Upgrade your vehicle's interior lighting with this aluminium car roof light, designed to replace or enhance existing fittings. It features a modern double-tipped decoding reading light design, constructed from solid aluminium for a durable and lightweight housing. The product is offered in four specific size configurations—31mm, 36mm, 39mm, and 41mm—each with a corresponding number of LED lights to provide the right level of brightness for reading or ambient cabin light. Operating on a standard 12V DC vehicle electrical system with a 150ma current, it delivers efficient and reliable illumination, finished in a clean white colour to suit most interior colour schemes.
Features and Construction

This roof light is defined by its precise specifications and material choice, offering a practical upgrade path for various vehicles.
Material and Build
The main housing of this roof light is fabricated from aluminium. This metal construction provides a balance of strength and low weight, which is advantageous for overhead fittings in a vehicle. Aluminium also offers good resistance to corrosion, contributing to the product's longevity in the varied temperature and humidity conditions found inside a car. The build centres around the double-tipped decoding design, which gives the light its distinctive appearance and functional shape for directing light.
Size and Practical Fit
A key feature is the availability of four exact size options: 31mm, 36mm, 39mm, and 41mm. These measurements refer to the overall diameter of the light unit. Each size is paired with a specific number of LED lights: the 31mm model has 18 lights, the 36mm has 27 lights, the 39mm has 30 lights, and the 41mm has 33 lights. This range allows you to select a unit that either matches the dimensions of an existing roof light aperture for a direct replacement or choose a size that fits your custom installation plans, ensuring a secure and professional-looking finish.
Uses and Placement

This light serves a specific function within the vehicle, providing illumination where it is most needed for practicality and comfort.
Event or Professional Use
For users who utilise their vehicle as a workspace or need reliable light for specific tasks, this roof light is a suitable upgrade. Its bright, multi-LED output in the chosen size can provide clear illumination for reading maps, documents, or device screens during nighttime travel, roadside checks, or for ride-sharing drivers verifying passenger details. The 12V DC compatibility ensures it integrates seamlessly with the car's power system without requiring complex modifications.
Everyday Home Use
For daily driving, this light enhances the cabin environment. It offers a brighter and potentially more focused light source than some standard factory-fitted roof lights, which is useful for finding items in the footwell or on seats after dark. The clean white light and modern double-tip design can refresh the look of an older car's interior. It functions as a general cabin light when doors are open and as a dedicated reading light for front or rear passengers when switched on independently.
Benefits and Buying Value

Choosing this specific roof light presents several practical advantages based on its stated specifications and design.
Reuse and Low Maintenance
The aluminium construction is chosen for its durability, suggesting a product built to last. Unlike some plastic housings that may become brittle over time, the metal build should better withstand repeated use of the switch mechanism and general vibrations within the car. The simple electrical specification (12V DC, 150ma) and lack of moving parts beyond the switch indicate a design focused on reliable operation with minimal need for maintenance or intervention once correctly installed.
Why Choose This Product
This product stands out due to the concrete choice it offers. The four clearly defined size and light count options (31mm/18 light, 36mm/27 light, 39mm/30 light, 41mm/33 light) allow for a tailored purchase. You are not buying a generic 'one-size' unit that might not fit properly; you can select the exact model based on your vehicle's requirements or desired brightness level. Combined with the aluminium metal housing and standard 12V operation, it represents a straightforward, specification-led upgrade for your car's interior lighting system.
