3.5. 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 P21Wusually drawn 21W,
when our LED-RED [≈P21W] has a wattage of 1.9W. The gap is then 21W-1.9W = 19.1W. This means that to
compensate this gap of wattage, you should use a Philips 21W CANbus.
3.6. How do I install a CANbus adapter?
If your car has a dashboard error message, experiences fast flash or goes in limp mode upon installation of an LED
bulb, you may consider to purchase and install a Philips CANbus adapter solution.

3.7. Why does this polarity issue occur with LED?
Regular incandescent bulbs can draw current in either direction, there are no "positive" or "negative" sides on the
bulb. The bulb will work regardless of which direction it is inserted. LED bulbs, however, only draw current in one
direction. Basically, this situation can be compared to batteries that have a positive and negative side. So if the
LEDs are inserted incorrectly, they will not work. The solution is to simply flip the LED.
3.8. After installation of the LED, my car show fast flash errors as if my light is out or broken?
Error messages appear because the LED bulb wattage is much lower than conventional bulbs, which can make an
outage warning system unable to detect the bulb.
If your car shows fast flash upon installation of an LED bulb, you may consider to purchase and install a Philips
CAN-bus warning canceller solution.
