The Philips LED CANbus Warning Canceller Adapter Pack eliminates dashboard error messages, hyper-flashing, and light shutoffs caused by upgrading factory incandescent bulbs to energy-efficient LEDs. Onboard automotive computers (CANbus) often misinterpret the low wattage of LED signaling and interior lamps as a burned-out bulb; these genuine Philips warning cancellers bridge the electrical gap to restore normal system operation. Available in 5W (12956X2) for interior/signaling bulbs and 21W (18957X2) for exterior signaling applications, each module features easy wire-clip connectors for effortless installation. Available through HID Concept.com, these adapters provide a clean, reliable solution without cutting or altering your factory wiring harness.

Questions & Answers

Need CANBUS compliant led adapter for 7443 brake light led. I need two sets, 1 set for each vehicle. What is correct PN ? one vehicle uses red bulbs, other uses white.
Which CANbus adapter do I need: 5W or 21W?
The 5W CANbus is used for interior applications, and license plate lighting. The 21W CAN-bus is
used for exterior applications such as position light, low/high beam lights.
Always refers to the original wattage of the halogen/conventional lamp. As an example, a P21W
usually draws 21W, when our LED-RED [≈P21W] has a wattage of 1.9W. The gap is then 21W1.9W = 19.1W. This means that to compensate this gap of wattage, you should use a Philips 21W
CANbus.
Even after installing LED with CANbus adapters, I still get an error message or flickering, what
should I do?
Even after proper installation of the LED upgrade and the CANbus adapter to remove any
flickering and/or error message on the dashboard, you still get the mentioned issues, this means that your vehicles is not equipped to handle LED aftermarket bulbs, even with the CANbus. -
Do you have an installation wiring diagram for the 21w canbus?
Fourth pictures in the listing product photos shows theinstallation diagram.
