In the video below we’re discussing one more common issue found in Alfa Romeo 147, GT, and 156 models. The light bulb warning light which is primarily used to detect defects in the lighting system of the vehicle is activated due to the faulty headlight leveling motor. While you might be able to replace the motor without taking the headlight completely off, you shouldn’t replace it before you reseal the headlight itself. This means that you will have to disassemble the front bumper to get to headlight mounting points. The job does involve some labor, and if you are not confident in your skills, you shouldn’t attempt to do it yourself.
