hi guys, i posted a message on here a couple of weeks ago because i had a problem with one of my xenon head lights not working. it has now been repaired but id like to inform you all wot happened. the ballast which controls the power to the bulb had actually faulted not the bulb, and the garage tried to pull a fast one and tried charging me £112, i argued and found out that the bulbs are a 100% under warranty, this also extends to components relating to the bulb thus being covered aswell, lets just say i left with a smile on my face.
