Not quite what you would expect from the title of the thread,
Originally I had a headlight warning (low beam) I think it said I fixed this replacing the blown bulb then it changed to Breaklight warning on the dash for a while until I discovered the sidelight takes over when the breaklight bulb blows so I replaced that but still had the warning then discovered the other side had gone aswell, I then discovered on the nearside rear there is a bulb that has no function (im guessing its a foglight for a LHD vectra but not used?) anyways I used that to replace the blown breaklight this then fixed the Breaklight warning. Now I have no warnings at all I can even now see the radio station, the only problem is my other headlight bulb has blown but no warning, I also have an ! when ever I start the car then it goes out immediatly.
Do I have a problem or should I just change the bulb and not worry about the warning for it not working?
