Most folks in the east hunt them in the daytime. The easiest way to figure out if any are about is to just ask the local farmers. Go down to the Co Op and ask. While farmers are particular about deer and turkey hunters, they don't seem to mind predator hunters at all.
As far as lights, it doesn't matter if they are red, white, or purple. Just like raccoons and possums, they aren't shy about lights. Now if you are turning them off and on it is a different story.
Varmint Al's site is great! I've built two sets of shooting sticks that I use and I just finished building the "El Cheapo" predator call. I downloaded some additional online sounds to add to mine. When I tested it out, I could still hear it from over 600 yards away! That tells me I was calling almost too loud, but you get the picture.
If you have the Sportsmans Channel, you are in luck. They have three great shows on predator hunting: Predator Nation, Predator Quest, and Predator Pursuit. These are all in the west though and I've got to tell you with the exception of calling it isn't applicable to the east. Lookup Eastern Coyote Hunters and they have a great site and purchase the video. That is a lot more help to you than watching what they do out west.

http://tnpredators.com/index.phpI haven't shot one yet, but now that I've seen a few it makes me happy to know that they are around where I'm hunting. The really nice thing is I'm scouting like crazy for squirrels, raccoons, possums, and other game. While I haven't got a coyote, I've found lots of great small game hunting locations. I'm sure when I tell them I'm hunting with air guns, they won't mind me coming back for some other stuff. The other thing I've found is lots of places to shoot CROWS! Oh my gosh how they come to predator calls!
