its illegal everywhere around here.
Ive seen people trying those green bait light tubes..but do they really work?
I have heard of flashlights in weighted mason jars working well... going down a closely drilled hole.
On the boat, we just toss 'em over the side, Ice fishing we us a light about 10-15 feet away from the hole with the line in it.Fish like the "edges"of the light the best, where they can easily dart into the darkness if they feel threatened.
