Keywords

What are LEDs?

Light-emitting diodes (LEDs) are essentially a type of modern lightbulb that are more efficient and tend to last longer than traditional bulbs.

More technically speaking, they're semiconductor devices that emit light when an electric current passes through them.

Cars use LEDs because they provide brighter and more focused illumination, enhancing visibility and safety for both drivers and pedestrians.
