4. In-situ design: plug and light without changing the circuit;
5. The aluminum parts are actively dissipated, and the heat dissipation effect is fast;
6. Less solder joints to improve product quality

if need install 4pcs at the same time, very few cars will cause error or hyper flash issue, please buy resistor together to solve the problem, 4pcs bulbs need 1pair 25W Resistors.


1.Please check whether your car needs a CANbus adapter before buying:
Remove the bulb, then turn on the bulb switch. An error code appears, indicating that the car has CANbus. European and newest vehicle equipped with CAN-BUS system may require load resistors to bypass the error codes/flicker issue when intall as DRL, turn signal and brake lights.

2.Our lights are suitable for 98% of the cars on the market, but for some very old decoded cars: Volkswagen, Mercedes, BMW, Kia. Opel, Renault, Hit, Logo, Skoda. Newer Jeep, Dodge, Chrysler or certain European vehicles may also need to add anti-flicker wiring harness or LED headlight decoder.

3.With DC 12v power supply, it can be judged whether the bulb itself is working.

4.Please confirm your socket before making an order. Thank you.
