Remember when working with animal/creature masks, the performers
vision apertures do not have to be located in the same location as the character's eyes. Look at the Masks for Lion King where the entire mask is actually above the actors head. Other examples have dark cheek hollows covered with a see through mesh. I know that Coyotes don't have long necks, but when doing things like a giraffe, the actors
vision holes can be hidden in the neck, again with a see through mesh.
As for the red glow, as josh said, get a couple of bright
LED's or flashlight lamps. Most hobby shops have little light kits for sweat shirts of costumes, some even have a small
dimmer. A quick look will show you you can
build your own for half the price. A little solder, batteries,
wire and a
switch, BINGO. The battery pack can be located either in the costume or in the mask head depending on the size and design.
