Because electric current is very small, led car bulbs with built in resistor.

Although car led bulbs are very brighter, flicker and hyperflash can’t be removed 100%.

When happening this problem, we have to built with resistor for car led bulbs.

Because a resistor will add electric currents for car led bulbs.

All of our car led bulbs are all building CANBUS error free design now.

And also our car led bulbs are all very long life time and brighter.

For example, most of our car led bulbs will be 50000 hours.

Welcome all people come to talk with us led car bulbs with built in resistor at any time.
