My ??? is who has a light adjusted to 200 ft. in front of them. Also if you've ever fished Herrington, you would know exactly what their talking about. It's without a doubt one of if not the worst lake in the state of KY. If you don't want you boat trashed run a headlight. If you don't care just run it a time or two without it & I'll bet you will run it after you get your boat back from the shop. I personally run 1 Stan Sloan 60 watt mounted to my trolling motor bracket & it is more than enough light & definitley doesn't bother oncoming boats nearly as badly as a spotlight. How do I know this ??? Because I've asked other boaters about it & even had 2 different buddies intentionaly drive towards me to see what it's like. They're nothing compared to a spotlight & the only way to go in my opinion. Spotlight users should give them a try. I think they'd like them.
