DAWNKNIGHT K5C110W H7 H4 Led Lamp Double Copper Tube Led Lights For Car H11 HB3 9005 HB4 9006 Canbus Led Headlight Bulb 2PCS

The new side-by-side double copper tube design reduces the probability of failure and is more reliable and stable.
High-power LED chip, brightness increased by 400%.
High-speed ball fan for better temperature drop.

K5C and K4C use the same color LED chip, but because the brightness of K5C will be higher, the color of K5C will look lighter than K4C.

If you are pursuing the perfect STG cut-off line, then K5C is a better choice than K4C!

Special reminder:

1.Some vehicles need to install additional decoders after using K5C, otherwise the following situations will occur

The bulb on one side is not bright.

The bulb goes out immediately after it is lit.

The occurrence of these situations means that you need an additional decoder.

2. Installing LED bulbs is a modification, and not all cars are suitable. Some models need to disassemble the front bumper to install the LED, and some installation costs may be required. We will not be responsible for any installation costs. Please try to light up the LED and test before installation to ensure that there is no abnormality before removing the front bumper to avoid unnecessary costs.

3. H1 is not equipped with copper pipe due to size limitation.

4.If you plan to buy the D1S D2S D3S D4S model, please pay attention to its size! Because most lenses have relatively small holes, our bulbs cannot enter, so you have to modify them to enlarge the radius of the holes! At the same time, these bulbs cannot be connected to the ballast, which means you have to disassemble the ballast, and then connect the LED to the 12V power supply.

5.K5C LED have a temperature adjustment function. As the temperature of the bulb rises, the power will drop to a certain level. This is a normal phenomenon and will help the bulb to prolong its service life. The power provided in the data is laboratory data and does not represent the power after long-term work.

6.This product is not suitable for use in fog lamps, sediment will reduce the life of the cooling system, if you need to use it on fog lamps, please contact the staff, we will recommend more suitable bulbs for you
