Thank you so much for the writeup. I just replaced my driver's side angel eye bulb using your method. I was a bit careless (read: stupid) and the tip of my dremel hit the old bulb, making tiny glass fragments explode everywhere. Had I not been wearing a face shield things could have been really bad.

Eye protection is very important whenever working on cars or using power tools, even on small jobs like this.
