Sounds like a good idea to me! I have been an avid duck hunter for since my early teen years. Fortunate enough to guide on one of the best Commercial shooting preserves in the South, "Dorchester Shooting Preserve". Enjoy watching other people enjoy themselves. One of the guests gave me a little light that attached to brim of my cap. It wasn't long before I started using it in the boat. Also, have used those little inexpensive battery operated closet lights that you just bump and it comes on.
Its like one of those cheap digital clocks that also has light in it. Just stick it up and when its gone buy another. Best deal may be those throw away glow sticks from halloween (if you ain't scared of goblins)--they are really cheap after halloween is over. Those little propane heaters give off some light and lots of heat. My Dad puts several granite rocks on top to put in his pocket to keep his hands warm. If you fish with him, he let you use one of the rocks but you have to pay $1.00 to get a second one. He grew up in the depression and can't help making a dollar. Uncle Tom
