When some cars replace 7443 led bulb, they are hyperflash or flicker.

At that moment, you need to put 7443 led bulb with built-in resistor in there.

Because electric currents is much less than halogen bulb, BMC of car is imcompatialbe with 7443 led bulb.

Frankly speaking, 7443 led bulb with built-in resistor means add electric currents.

Our 7443 led bulbs are all CANBUS error free design, which can remove 90% hyperflash problem.

In order to make you clearly our 7443 led bulb, I will show you picture as below.

If you can give my factory a chance, I am sure our 7443 led bulb must have a ready market.

Welcome all people come to talk with us 7443 led bulb with built-in resistor at any time.
