My LED doesn't light up after installation. Why does this happen and how can I solve this?
If your LED doesn't light up, its likely that you need to flip the LED.
Why does this happen?
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!
Follow these steps to reverse the polarity:
- Remove the LED from the socket.
- Flip the LED.
- Insert LED back into the socket.
- Check to ensure the LED lights up.
After installation: I notice fast flash or dashboard errors about a failing bulb. What should I do?
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.
In some vehicles that are equipped with a CANbus control system, the installation of LED bulbs may cause error signals on the dashboard.The Philips Vision LED warning cancelers, avoid the error signals caused by the failure diagnostic of the CANbus system.
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 Vision LED CANbus warning canceler solution. The 5W CANbus is used for interior applications and license plate lighting. The 21W CANbus is used for exterior applications.
