Since my technical skills with cars are pathetic to say the least, I decided to go online just to see if there was anything unusual about changing the headlight.
Is it really necessary to remove the entire assembly? https://www.youtube.com/watch?v=rGO0p5bDUi4
I can't imagine that the car was designed to make it THIS much effort to change a burnt out headlight. I will tackle it tomorrow- but I assume this is not really needed?
