no lites would be better than any lights in the snow like that. You'd be better off getting a cheap GPS if funds are tight. A good one is better obviosly, but as long as you have a direction and or a path you're fine
I had no directoin at all and there were no sled tracks cause it was snowing. I couldnt even see where the shore was. Don't fog lights make it alot easier to see in snow and fog because they're mounted low to the ground or something??
