I’ve just installed LED down lights in bathroom and hallway. The light in the bathroom is a single LED and turns on/off correctly. There are 4 LED lights in the hall connected to a Trailing Edge dimmer switch. These operate normally, however, when the hall lights are on and the bathroom light is switched on it occasionally turns the hall lights off. They are all on the same lighting circuit. I’ve checked the wiring and am sure I’ve done it correctly but am perplexed on what I’ve done wrong. Any ideas?
