Bought these to replace the flickering lightbulb in my old Clairol True-to-Light 7 vanity mirror I had to press the 2 bulb pins together slightly (with a pliers) to snap them into place, but they fit! (Unscrew all 4 screws on the back of the mirror to access the lightbulbs). Although I only had one bulb, I replaced both because the new bulb made my complexion "pink" on that side of the mirror than the original bulb's side. (There are 2 new bulbs in the photo.) The bulbs were packaged very well. They arrived in a small box and were tightly wrapped in styrofoam tubes for protection.
