The usage rate of LED car bulb in China is less than 1%, which have a greater gap compared with New Zealand and other countries whose usage rate reaches to 30%.

The main obstacle in China LED lighting market is cost. LED chip production technology is difficult, the threshold is high, the temperature, humidity and power supply for the raising process if crystallization is very strict, the initial need to invest heavily to build factories.

Currently, Taiwan is the main source of LED chips, which occupies 47% in the LED market, while LED industries in mainland China is more for the resin package processing, LED chips requires a lot of imports, which is a major cause of high cost; the other is that the domestic auto industry manufacturer and consumers are lack of awareness of LED auto bulb, who are used to making comparison of cost between LED auto bulb and traditional lights, which impact on the rapid pace of LED auto bulb industry.

Third LED brake light 

LED Car brake light

With the increasing pressure of energy saving, the government has initiated various support policies and measures on LED light for car industry before and after 2007. So far, there are more than thirty manufacturers who are with the scale of the upstream chip enterprises who take package products as main are concentrated in the Pearl River Delta and Yangtze River Delta region, its production capacity has occupied 60% of that in the world; downstream end application product is more substantial, estimating that only in the Shenzhen have nearly 3,000 enterprises  of LED car bulb packages and applications.


2011, with the further support of the government policies, LED car bulb companies are now shown a blustery, persistent and strong momentum. In recently two years, there are as many as 50 so-called establishments of national and global “best” of optoelectronics industry parks, even some third and fourth level of the counties and cities have claimed to create the world’s largest Photoelectric Industrial Park.


We can’t predict the destiny of the so-called “largest” corporate after 5years and fear that the result of this herd will be littered with felled. Fierce price competition will not only form a huge waste of human, material, resources and land in the end. However, the ultimate winners from a pool of blood in blaze will be easily grabbed by the giant international lighting or international capital.


We call for industry hero to dream of a “miracle”, but these dreams have to established based on the sense of quality and attention to personnel training. Enterprises without brand awareness will be not long-term wherever they go.


Companies who do brand, quality and reputation will go further in the LED light for car industry.

If you have not heard about the new varieties of car light, please make depth understanding of them. Don’t purchase products like the “vacuum halogen bulb”, it is pure fake.


Be clear what’s the light bulbs used for and whether it is car light bulb, which parts is the car light used to. Please be careful about it.


Is the car “search light” a member of the auto headlights?

Car “search light” is irradiation distance, a special optical design, high efficiency reflector and strong condensing. The irradiation distance can be up to 1200meters. Car search light can be widely used in railway, electric power, public security, steel, petrochemical, car light, patrol vehicles and so on. In recent years, car search light has been openly applied in many cars and agricultural machinery parts for its advantages of strong condenser and irradiation distance.


As the search light glares so strongly that seriously impact on the safety of driving at night, so we must stop using it. The standard headlamp light is a national promotion dimming light bulbs, including R2 and H4 fog light series, whose illumination values and dimming performance can meet the requirements of driving safety.


Does “vacuum halogen bulb” exist?


The “vacuum halogen bulb” appeared in some auto parts market is actually a “vacuum bulb”. Vacuum lamp bulb is the simplest making procession in light family, which is life shorter and luminous flux lower compared with the inflatable bulb.


Speculators take advantages of the less understanding for light bulbs of the consumers to promote the so-called “vacuum halogen bulb”. Here remind consumers not to be deceived by these tricks.

This three kinds of LED auto lights introduce to you is hot selling, which will be the best combination for your car tail light! Have a try right now!

BMW tail light is made up of turning light, brake light and reverse light. Its emitting colors are yellow, red and white.

 Socket of turning halogen light (turn signal light) bulbs is P21W, bulb diameter is 26.5mm, length is 52.5mm, power is 21w. Socket of tail halogen light (brake signal light) is P21/5W, bulb diameter is 26.5mm, length is 52.5mm, power is 21/5w. Socket of reverse halogen light is W16W, that is W2.1*9.5d, bulb diameter is 15.2mm, length is 35.6mm, power is 16w.

 Since LED materials is no delay, energy saving, long life, low heat, high color purity and more advantages, LED auto bulb has been the necessary alternative. LED tail lights are also widely used in various automotive brands such as Audi, Mercedes, Toyota and other models, and become a new selling point for vehicles.

 Then what are the specific models, specifications and parameters? What should you pay attention to when you select car LED tail lights

 According to the common sense of car lights, we know that LED light can be used instead of halogen bulbs which must be interchangeable in the base. The correspondence between halogen bulbs and LED auto lights is as follows: P21W=BA15S, P21/5W=BAY15D, W16W=W2. Therefore, the models of LED turning light, LED brake light, LED reverse light are T25BA15S, T25BAT15D, T15W2 for the BMW LED tail light. The related light power depends on the LED quantity, structure and other specific calculations.
