An LED car bulb is a type of light bulb that uses light-emitting diodes (LEDs) to produce light. LED bulbs are more energy-efficient and have a longer lifespan than traditional incandescent bulbs. They are also more durable, making them less likely to break or burn out.

LED bulbs are available in a variety of shapes, sizes, and colors. You can find LED bulbs that fit into your car’s existing headlight housing, or you can purchase aftermarket LED headlights that replace your entire headlight assembly.

LED bulbs are a great way to improve the look of your car and make it more visible to other drivers on the road. If you’re looking for a way to make your car stand out, LED bulbs are a great option

History of LED Bulbs

LED lights made their debut in the first vehicle models around 20 years ago. Initially, they were installed in taillights and brake lights, and later also in turn signals and daytime running lights. In the meantime, LED lights are also used for low beam and high beam and have almost completely replaced halogen and xenon lights.

Advantages of LED Bulbs

There are several advantages. For example, LED lights are often brighter than halogen lamps, more energy-efficient, and longer-lasting. Or LED lights with matrix technology: They consist of many small, separately controllable LEDs, and can specifically cut out oncoming cars or the vehicle in front. Their drivers are then not dazzled, but the surrounding area is well illuminated and obstacles are detected earlier.

Why can LED lamps break?

LED lights generally last longer than halogen lamps, but they don’t have eternal life either. The reason: they wear out over time, and the luminosity decreases over the years. If the emitted luminous flux falls below 70 percent of the original value, the LED light source is considered worn out.

When this occurs depends very much on the cooling and heat dissipation of the LED modules, especially that of the semiconductor layer (“junction”).

This is because, unlike incandescent lamps, LEDs are very sensitive to temperature: the higher the temperature, the greater the wear. A very warm environment such as a hot engine compartment, a radiator or air-conditioning condenser near the headlamp, and high outside temperatures can shorten the service life of the LED just as much as light output and thus power loss that is too high for the ambient conditions.
