I agree with dm, dark nights they are great. If you have any other light source moon, another boat, dock, etc they are not very effective. I have 20/14 vision and they work good for me but I have to break out the moon lights for my partners sometimes. Ease of use and no storage needed makes them worth while. Dark nights a Dale you will love them. Drive 25 miles up the rode to the damn at Cumberland and you cant even tell they are on. I have 4 on a side on my cougar ftd and use flo fc that is not as bright as mono. I thought all the boys down your way had switched to braid anyway to roll them big blades deep? The cool thing is you can use them all night and when your head hits the pillow and eyes shut you dont see a laser light show!!! I have a lot and fifth wheel at kendell if you want to see mine we could hook up. Dont know which end you are on but either way it would not be too difficult.
