Built-in CANBUS is Very Important for LED Turn Signal Light

We know, most LEDs may cause hyper flash & error code when they are replaced on the turn signal lights due to LEDs low-consumption, energy-saving performance. If there isn’t enough resistor value to meet car computer, extra resistor decoders will be needed.  

Now, there is a good solution to abandon annoying resistor decoders. Our new version CANBUS 7440 will meet your need. LASFIT is the first brand on the market to publish built-in CANBUS Amber & Switchback LED turn signal lights, when most products of LED are not canbus error free on the automotive aftermarket. We are confident that these bulbs would give you an extraordinary driving experience!
