Watched your 'how to' video at least 50 times. And, I still wasn't all that confident. Murphy's Law, don't 'cha know.
My Amana electric stove oven light was a little different than the one in the video, but the video gave me the insight to pry the flanges.
By golly, it worked! Out came old - in went the new!
A slam dunk! No sweat!
