You may need extra load resistor
For some CANBus vehicles, the electronic computer may detect the wattage loss after installing LED bulb, it then may launch warning message to drivers, such as bulb hyper flashing, flickering, radio interference, malfunction error code on dashboard. At this moment, you need to install extra 50W 6OHM load resistors to help reach the same wattage that halogen produced, and then eliminate the malfunction.
