If you are having flickering problem or there is warning on dashboard "Bulb Out" or "Bulb Failure" , our error canceler is the solution. Installation really simple, plug and play! Install this between ballast and power supply.

You should know that it is not bad quality ballast or bulb but the 35W OUTPUT that causes this problem. So usually, you can use 55W ballast kit to avoid this problem.
I installed an HID kit on my 2009 Mini Cooper S. After the install I got a bulb out warning on my dash, so I thought these would solve my problem. They were easy to install, The description says these work on BMW's , no issues. They worked well and no feedback into on-board computer.
