What is the relationship between CK and Double non-polarity?

Double polarity means we makes the 1157 3157 7743 bulbs be double non-polarity. 1157, 3157 and 7443 bulbs have high beam and low beam. So when we want to make these bulbs non-polarity, we will need to put two pcs of no-poparity components in it. That is called double non-polarity. CK is a different concept. Just because the led bulbs with double polarity deisgn can be compatible with the CK wiring, so they are commonly discussed together by people.

Why the power of two led headlight bulbs (one kit) are different?

That is because the electronic components has a floating range value on parameters. We have indicated the product working current with a floating range value. This is unavoidable.

When installing a led headlight in car and turning off the engine, the led headlight is still on and have a little light. And the problem won't be solved although connecting the led headlight with a decoder.

A little current will left in the circuit although you turn off the engine. And LEDs can light up with small power supplied. Our 2in1 headlight mate can solve this problem.

Will the led bulb have problem as the operating temperature is high?

If the heat sink of led headlight is hot, that means the heat transfer well from LEDs to heat sink. Will the led bulb have problem because of high operating temperatrue? It depends on whether the operating temperature is continuely higher than the Junction temperature of LEDs. Please refer to our led headlight for more details.
