01. Dash Board Error Message:

As we all know, many modern luxury cars have their computer systems built into the dashboard. The computer system will detect whether the sepecifications of the replacement bulb match the original bulb. However, LED bulb is more energy saving with lower output power, which means the computer system will misjudge the LED bulb doesn't match the wattage of original system, then there will be an error signal showing on your dashboard. In this situation, we need to adjust the wattage to meet the computer default parameters. Basically the bulb will match perfectly by installing a resistor to enlarge the wattage. Recommend our CANBUS LED headlight which is compatible with most luxury cars, especially European cars.(the models built in constant current, non-polarity, anti 18V electrical surge will much better to solve the problem)

02. Flash Speed for Signal/Turn Light:

Normally, when you turn on signal lights, two side of turning lights will flicker at same slow speed. However, if you have modified your light to use LEDs for some Luxury Cars, you'll notice that the turn signals now flicker very quickly. It is caused by the low resistance of the LEDs due to the fact that they use less energy. To solve this problem, you need to install a resistor or control flasher. (Our CANBUS LED headlight also can avoid this kind of problem on most cars.)

03. About LED Chips Power and Operating Power:

"POWER" in specification is the power of LED CHIPS, not the working/operating power of the LED headlights, WORKING/OPERATING POWER=DC12V * CURRENT;

For example: H7-4*5W: It's so-called 20W in this industry, due to it's made by 4pcs of 5W Cree LED chips, But its working/operating power is only=DC 12V * 0.3A=3.6W (ranging from 3.6W to 5.0W actually), IT'S NOT "MORE POWER, MORE LUMINA", CERTAIN SMALL POWER MAKES LED CHIP WITH MORE LUMINA AND STABILITY.
