12V Car Reading Light 12 LED 3W Interior Dome Light 31-41mm Universal Fit Replacement for Door Roof Map Light White Colour Interior Lighting
12V 12-LED Car Reading Light 3W White Universal Interior Dome Light 31-41mm

Original factory interior lights often produce dim, yellowish light that makes it hard to read maps or find dropped items at night. This 12V LED reading light solves that problem with 12 bright white surface-mount LEDs delivering 3 watts of output. It is designed as a direct replacement for standard car interior bulbs, fitting roof lights, door lights, map lights, and taillight positions. The universal build fits most vehicle models without any circuit modifications, so you can upgrade your cabin lighting in minutes. Available in four diameters from 31mm to 41mm, it matches common socket sizes. For other luminous colours, contact customer service before ordering.
Features and Construction

This LED unit is built around a compact circuit board housing 12 SMD LEDs. The white light output improves visibility for reading, searching the cabin, or working inside the vehicle at night. The low power draw of 3W makes it an efficient upgrade compared to standard filament bulbs.
LED Configuration and Brightness
The light uses 12 surface-mount LED chips arranged to provide even, shadow-free illumination. Rated at 3W total power consumption, it offers significantly more usable light than a typical 5W or 10W incandescent bulb while drawing less current from your car's electrical system. The white colour temperature improves contrast for reading small print or maps.
Size and Practical Fit
Available in four diameter options: 31mm, 36mm, 39mm, and 41mm. Each size is designed to slot directly into the spring-metal clip holder found in most vehicles. A small tolerance of approximately 1mm exists, but this does not affect installation or secure fitment. Choose the correct size by measuring the original bulb or socket opening before ordering.
Uses and Placement

This universal LED light is intended for use in various interior locations where standard 12V bulb replacements are needed. It works equally well in cars, vans, and SUVs without any wiring modifications.
Event or Professional Use
For taxi drivers, delivery professionals, or anyone who spends extended periods inside their vehicle, the improved light quality makes paperwork, map reading, and item location easier. The white light reduces eye strain compared to yellow interior bulbs.
Everyday Home Use
In personal vehicles, this light upgrades the standard interior lighting for better visibility when entering or exiting the car at night. It is particularly useful for families who need to find dropped items, read directions, or attend to children in the back seat.
Benefits and Buying Value

Replacing interior bulbs with this LED unit offers practical advantages beyond simple brightness. The low power consumption reduces strain on the car battery when lights are left on accidentally, and the long lifespan of LEDs means fewer replacements over the vehicle's life.
Reuse and Low Maintenance
LED chips typically last tens of thousands of hours, so this light should outlast typical car usage without needing replacement. There are no filaments to break or burn out, making it a fit-and-forget upgrade.
Why Choose This Product
At 3W with 12 LEDs, it provides a strong brightness-to-power ratio without requiring any wiring or modification. The multiple size options cover the majority of standard interior light sockets. Choose the size that matches your vehicle's existing bulb housing for a straightforward swap.
