We have the same problem bowfishing as we must have yellow colour also I've noticed coons are also less shy from the halogen when in the boat.A quick fix for bowfishing is putting cellophane over the led light.You can buy it from any local arts and crafts type store.Jus pick your color and tape it on.This the colour I used.
Don't know if it will work for y'all but it helped me when the halogen died early in the night.
