This may seem like a silly question but ... There are recessed lights in our bathroom and they have been changed about every 2 - 3 years. In the past it was a source of frustration for my husband to remember how to remove the clips and get the cover off and change the light bulb. And he was quite the handyman so I do not say this lightly. Sadly he has passed and now it falls on me to figure out how to get this cover off and change the bulb. Any suggestions about removing this light cover. My guess is that this particular fixture was produced in circa 1970. It has about a 4" diameter and appears to have some kind of metal clip that holds the cover in. I just can't seem to remove the cover.
