You probably just need to isolate that light, give it its own circuit. First thing to check would be your primary service, it should be 100amp, to meet code, I installed 200amp for mine because it was only 60 amp, and the difference in cost was minimal. Assuming you have adequate service, look in your breaker box and see if the circuits are identified, ie 2 Kitchen, 3 Dining room etc. If not its time to find out which switch is which. This is best done with some helpers, turn them all off, then on one at a time. You have to have at least one 110volt that is 10 wire or bigger that goes to your kitchen, maybe its accessible? There are options to look at, I installed all of mine from the post in the ground that the meter is on to final inspection, you can do what needs to be done. Its easy as abc, black white green. VV
