I have two linked recessed lights in my kitchen that are linked to two switches on opposite sides of the room. One light flickers. I checked all the connections and they're tight. I changed the bulb to a lower wattage. The other light does not flicker. It's on a 15 amp circuit and is connected to other lights throughout the house. They don't flicker. I don't think it is tied to an excessive load on the circuit because i have watched it flicker when all other lights/appliances are off. But I'm not entirely sure of this. If the flicker is related to excessive load, would only one light flicker and not an identical recessed can right near it? Any idea to help me check/resolve the issue would be appreciated. Thank you in advance.
