K8C 40W Product Description:

1. K8C 40W is modified on the basis of K7C, reducing the power of each bulb to 40W and using smaller light-emitting chips. Although the size has shrunk, the luminous flux emitted under the same power has not changed, which means that the light will be more focused.
2. The chip change is not reflected in the H4 model, and the K8C 40W H4 model still uses the same specifications as the K7C.
3. The early version of K8C warm white is more like 5000K. We have recently made changes to the warm white color. The latest version of K8C warm white will be closer to 4300K, they will be warmer than the old color, same color as K5C 40W 4300K. But it should be noted that the warm white color we offer is different from halogen lamps. If you want to order the same color as a halogen bulb, our 4300K bulbs may not meet your needs.

Special reminder

1. Some vehicles need to install a decoder after using LED, otherwise the following situations will occur:

– One of the two light bulbs is off or blinking.

– A malfunction light appears on the instrument panel.

– After turning on the low beam, one of the bulbs switches on the high beam function uncontrollably.
These situations indicate that you need to modify the decoder.

2. Adding LED bulbs is a modification, not applicable to all models. Some models need to remove the front bumper to install the LED, and you may need to pay a certain installation fee. We will not bear any installation costs. Please try to light up the LED and test it before installation, and remove the front bumper after confirming that there is no abnormality, so as to avoid unnecessary costs.

3. LED has temperature adjustment function. As the temperature of the bulb increases, the power will drop somewhat. This is normal and helps to extend the life of the lamp. The power provided in the data is laboratory data and does not represent the power after long-term operation.

4. This product is not suitable for fog lights, deposits will reduce the life of the cooling system, if you need to use it in fog lights, please contact the staff, we will recommend a more suitable bulb for you.
