LED is the abbreviation for light-emitting diode, which fundamentally consists of a piece of electroluminescent semiconductor material placed on a leaded frame and sealed with epoxy resin to protect the internal core.

In addition, LED light sources have many advantages:
Voltage: LEDs use low-voltage power supplies, with supply voltages ranging from 6 to 24V, varying by product, making them safer than high-voltage power supplies, especially suitable for public places.
Efficiency: Consumes 80% less energy compared to incandescent lamps of the same luminous efficacy.
Applicability: Very small, each individual LED chip is a square of 3 to 5mm, allowing for the creation of devices in various shapes, suitable for variable environments.
Stability: 100,000 hours, with light decay to 50% of the initial.
Response time: The response time of incandescent lamps is in milliseconds, while the response time of LED lamps is in nanoseconds.
Environmental pollution: No harmful metal mercury.
Color: Changing the current can change the color; the light-emitting diode can adjust the energy band structure and band gap of the material through chemical modification, achieving multi-color light emission in red, yellow, green, blue, and orange. For example, at low currents, it emits red light, and as the current increases, it sequentially changes to orange, yellow, and finally green.
LEDs are known as the fourth generation of automotive light sources. LED car lights, although having a higher initial investment, possess advantages such as better quality and higher grade that incandescent lamps cannot compare with, and they have no delay, are energy-saving, have a short lifespan, low heat, high shock resistance, and high color purity, making them a necessary replacement for tungsten filament and halogen lamps.
Additionally, automotive LED decorative products are currently very popular both domestically and internationally. This is a new type of automotive decoration product that integrates safety, applicability, and decorative features. Due to the good waterproof and impact resistance of automotive LED chassis lights, they require no maintenance or cleaning, and their power consumption is equivalent to that of a car headlight, without overloading the car battery and engine during use. The product is installed at the bottom (or inside) of the car, and at night, in foggy, rainy, or low visibility conditions, it can effectively provide pedestrians or other vehicles with the location of your car while driving or parking, reducing the risk of accidents. When the LED lights are turned on at night, the bottom (or inside) of the car displays a variety of colors such as red, blue, and green, which is very beautiful and popular among young car enthusiasts.
