Have you installed an aftermarket HID kit into your euro automobile and noticed an error popping up on your dash? The general reason behind this is the fact that the CANBUS system in the vehicle monitors for a halogen bulb where as the HID bulb now uses less power. There are three options in this scenario. Either remove the lights and convert the car back to stock, attempt to code out the errors, or simply install a warning canceller module which will effectively 'trick' the computer into thinking that you still have halogen bulbs installed. We've tried the third option in one of our demo cars and it has worked a treat. Head on over to the store if you would like to try the third option too.
