I'm going to amend my suggestion, as coyotes will be even more deterred by brighter and floodier.
I read about a solar coyote deterrent that I can't believe works (and with Amazon reviews YMMV massively as it has been proven many of Amazon reviews are fake if not entertaining). Coyotes can only see light in the yellow and blue spectrum, and coyote hunters swear by red lights as they take advantage of this. IF it works, it must be because it blinks and has little to do with the color. Product page suggests it appears to animals like eye shine, the tapetum lucidum, but the notion that anyone can know what a wild animal is thinking is beyond ludicrous, especially when most of the time we can't even tell what a person we know well is thinking. And I also can't imagine something more annoying than a blinking red light outside my house. I think a bright flood on a motion sensor would be vastly more effective.
At any rate, to deter coyotes, you can't go wrong with very bright flood.
