DAWNKNIGHT K7C 4300K H7 H4 H11 Led Lamp 3 Copper Tube Led Lights For Car H1 HB3 9005 HB4 9006 12V Led Headlight Bulb

K7C product features:
1,The two versions of K7C 150W and 110W are quite different, please read this paragraph before ordering to decide which version to buy. 150W has higher power and higher brightness, but we only recommend using it in projector headlights; 110W adopts the design of K5C 110W version, which optimizes the driving scheme and heat dissipation system.
2,There is no significant difference between K7C 110W brightness and K5C 110W brightness, and K7C performs better in some projectors. Since the K7C has an extra copper pipe and the upgrade of the cooling fan, the working temperature will be about 8°C-10°C lower. And K7C's H7 H11 9005 9006 9012 models have added a temperature sensor for the chip position pair, which has a positive effect on protecting the chip from overheating.
3,Some Korean brand cars are not suitable for using bulbs with too high power, please consult us before ordering.

Special reminder: ​
1.If you plan to buy this model (D1S/R/C, D2S/R/C, D3S/R/C, D4S/R/C), please be prepared to modify the power plug. You cannot use any HID connector (AMP, KET, KET2, etc.) to connect this LED bulb. ​Before installing the LED, you need to remove the HID lamp ballast (ignition device), and the LED needs to be directly connected to the 12V power supply.

2.This high-power LED bulb needs to be installed by professionals. Some German or American brand vehicles may have an error message or flash and then go out on the dashboard after using LED, including one of the two bulbs going out. These situations are compatibility issues and require the installation of a decoder or adjustment of the on-board computer options. They are not within the scope of bulb failure.
