From our experience, "conditioning" or (coyotes getting used to seeing lights making it easier to call them to a white light) never had a direct impact on the way they reacted good or bad when hit with a light. Of corse, some areas they will get used to seeing lights more than others in more populated areas but to make the assumption that those coyotes will respond better to a white light in those areas may be a bit of a stretch (in my opinion). If anything, just understanding the nature of a coyote would make you question that logic just due to associating those readily seen lights with humans and danger. You can look at it both ways but from our experience, the ones that see the most lights are the hardest ones to get close and throw caution to the wind if that makes any sense?
Regardless, every coyote has his own personality that will vary from animal to animal based on the environment it's in and the experiences it has had in its life so conditioning can play a role but lights on the horizon in my cheap and humble opinion don't have anything to do with getting a coyote to you under a white light. For that matter, some of the ranches we've hunted in west Texas are some of the most desolate areas in the state with very little light and they act much more aggressive when trying to get to the call than they do here in north Texas and we hunt literally rite on the edge of towns with traffic and street lights all over the place.
No matter what, the one thing we do know to be a fact is CALLING a coyote under any color light and not getting it killed will greatly decrease the odds that coyote will keep coming the next time he gets hit with a light. I can assure you, that in itself will give a coyote a lifetime of education way greater than seeing lights on the horizon on a regular basis. You can take that to the bank. That's my two cents
