Just bought new flush mount ceiling LED lights. the light in the hallway has 2 switches to it and this light does not completely turn off when flipping the switch off. The tabs are always dimly lit. Is this normal? Should we be concerned about fire? Why does this happen? Is the light defective? Thanks
It's NOT dangerous, but annoying.
It's floating/induced voltage that exists due to the travelers between the switches run in parallel. You can prove this by pulling just one travelers off a switch on either end of the switch circuit (or if standard toggle light switch putting one switch in the non-existent yet functional 'middle' position which breaks the connection and doesn't keep one traveler wire energized).
One answer is buy higher quality bulbs, another is just ignore it.
