Instruction of LED

Advantages of LEDs in automotive lighting
LEDs have many advantages over the light sources conventionally used in automotive applications.
1. The very principle of the LED leads to a longer service life and increased reliability. The working principle means that the lamp can be used for 50,000 hours and more, depending on operating temperature and definition. The service life of filament and halogen bulbs is typically a few hundred hours, whereas the gas discharge lamps also used in automotive lighting manage a service life of several thousand hours.
2. In addition, the LED has significant advantages in resisting mechanical stress of the kind which occurs in vehicles.
3. Its compact design is another advantage. LEDs can be used to realize lamp systems optimized in terms of design space, reducing component height and thus saving space. This is supported by the high efficiency of the LEDs, which significantly reduces the heat produced by the complete lighting system, particularly in the case of colored functionalities such as the tail lamp and direction indicator.
4. Not forgetting the innovative styling options which result from the use of several light sources and new, LED-specific optic concepts. They provide vehicle manufacturers with new possibilities of disti nguishing between makes and models.
5. No UV Emissions/Little Infrared, LEDs produce no UV radiation and little heat, making them ideal for illuminating objects, such as works of art, that are sensitive to UV light.
6. Saving energy, LED lights’ power consumption only cost 1/5 of traditional bulbs. For example, a LED brake light cost about 3W instead of 21W from traditional brake light
7. Quick response time. LED light turns on in a very short time, according to test report, there is 0.3 second difference between LED bulb and traditional automotive bulbs. That means, if a car driving in a speed of 60km/h, there is 5 meter distance more for followers make response.
9. Less heat radiating. It can prevent the reflector from aging。

10. Different color temperature is available.
Auto LED buying guide.
Because different car has its own selection on bulb base, there is no a single form for matching LED with cars.
AUTO LED application just depends on the base. So one type LED may be used in different places in one car; or different type of LED lamps can use in same application of different cars
Here are hundreds of LED bulbs for automobile, but we normally divided them in to catalogue according the base.
T10 wedge (194);
T10 ba9s;
ba15s/bay15d (1156/7);
3156/7;
7440/3;
Festoon;
H series,(fog lamp)
and LED panel.
Generally speaking,
T10 wedge (194) is a wide use type. It can be used in side markers, turning lights, dashboard and corner & bumper lights, etc…
T10 Ba9s is almost same application with T10 wedge (194), but it normally occurs in old style cars.
Ba15s/Bay15d (1156/7); 7440/3; 3156/7 are used for brake light, tail light, turn signal light and backup lights. 1156/7 is a wide used one, normally, 3156/7 is or American style car and 7440/3 is for Japanese style car.
Festoon LED is used for license plate; step/courtesy; dome/map light
LED panel is used for dome/map light.
H series means H1 H4 H7 etc… they are used for fog lights.
If the car is with CANBUS system, such as BMW, BENZ, it requires CANBUS version LED. Then the warning will be cancelled. However, CANBUS LED technology nowadays can only solve most CANBUS problem, not all.
Pls note now only T10 and festoon series bulbs can use CANBUS LED.
If you want to know what bulbs for a certain car model, can go to /wizard1.php for checking. If a wholesale ask what the best seller is, just told him T10, 1156/7 and festoon.
Below pictures show the application of LED.
This picture’s LED is SMD LED, more bright but price also high.
This picture’s LED is LED lamp, less bright but cheaper than SMD LED. There also a mid class version we call FLUX LED, but no such a picture here.。
