Wasn't sure if this was the right forum to post in. We have a light bar in my son's bathroom (3 lights) that my husband wants to replace. The problem? Husband removed 4 screws - one on each corner of the bar. He can turn the bar around (only so far because of a mirror below) however he cannot pull the bar out from the wall. He can see part of the hole behind the bar which of course contains the wiring but that thing just refuses to pull out from the wall. Any ideas on what is going on? Thanks.
