Auto LED lights, with their energy-saving, high-brightness characteristics, have become the best option to replace halogen lights in cars. However, many people do not understand the details of LED lights, let's learn about it together.
Lumens are the units of brightness, which should be within a certain reasonable range. Too dim or too bright can affect the driver's sight. The discrepancy in lumen values of auto LED lights on the market is due to some merchants falsely claiming lumens or promoting the "theoretical value of car lights," making car owners misunderstand that it is the actual value.
Of course, car lights are not the brighter, the better. LED headlights have many advantages compared to previous halogen lights and xenon headlights, such as long lifespan, energy-saving and environmentally friendly, small volume, and fast startup speed.
The higher the LED current, the higher the luminous flux, but the increased luminous flux is not a linear relationship, but an exponential relationship. That is to say, when the current increases by twice, the light flux does not increase by twice, but only a little. Moreover, when the current reaches a certain value, the LED is damaged. LEDs have an optimal current value. The larger the current, the hotter the LED, and the faster it dies, so "higher is better" is not the case.
From the perspective of car lights development, starting from the most common halogen headlights, to xenon headlights, and then to LED headlights. The luminance gradually increases, and the visibility at night driving gets better and better. In terms of usage, the cost, lifespan, and power saving of LED lights and xenon lights are far greater than those of ordinary halogen lights. This is the reason why high-end cars come equipped with xenon headlights or even LED lights. However, halogen headlights also have advantages. They have better penetration in heavy fog or haze days. If you use xenon headlights with 6000K or above, the sight will become white and hazy.
This is also why turn signals and fog lights are required to be yellow lights. In other words, if we see the oncoming car with high-intensity xenon or LED headlights, it will also cause headaches and repulsion.
The principle and startup method of LED are different from that of xenon lights. It does not need stabilizers and will not produce high-voltage breakdown and other problems. However, each lamp is equipped with a power driver.
Adding a decoder is because the car computer detects abnormalities after upgrading the lights. Although LED has a low current start-up and does not interfere with most cars, some detection power car models need to install decoders.
For LED car light that replace the original halogen lights, the models correspond to the original halogen lights, and the clamp fits the lamp type. There are also a small number of cars with specially designed clamps. However, professional modification shops have corresponding clamps that can adjust the light shape, or solve most special-purpose car installation problems with a few clamps, so installation is worry-free.
Not 100%. Due to structural restrictions, a very small number of car models do not have enough space for the kit, and installation tests have not been performed for all car models. However, currently, the LED can cover more than 95% of the car models on the market, and most car models can be installed worry-free.
The differences in the quality of LED car light are in light shape, lifespan, heat dissipation structure, and the use of different materials. There is no significant difference in appearance, but the actual use and lifespan differences are enormous, so you do get what you pay for.
