How do I know if I need an LED resistor or canceler cable?

When installing LED fog or signal lamps, you will encounter problems on some vehicles with computer-managed electronics due to the difference in power used between standard halogen bulbs and LED bulbs. To save time and get your kit installed correctly the first time, you want to make sure you have any necessary accessories when you first order your kit, so you can avoid flickering, error messages and incorrectly operating lights.

To find out if your vehicle needs a canceler cable, follow these guidelines.

Are you using the LED bulb for a turn signal?
Nearly all vehicles will require an LED Error Canceler when using LEDs as a turn signal. The decreased voltage for LEDs often causes hyperflashing.

Does your vehicle notify you when a bulb is out?
Your vehicle has a CAN (Controlled Area Network) and will require an LED Error Canceler.

Do you have an Acura, Audi, BMW, Chevrolet, Chrysler, Dodge, Jeep, Mercedes-Benz, Volvo or Volkswagen?
Your vehicle likely has a CAN (Controlled Area Network) and will require an LED Error Canceler.

Is your vehicle model year 2006 or after?
Many vehicles in the United States sold after 2006 and most vehicles sold after 2008 have a CAN systems and you may encounter problems with your HID light installation. In these model years, an LED Error Canceler is recommended. However, we recommend researching your specific vehicle to be sure.
