Here is an example of one of my friend's boats with clamp-on AC lights.



-------------------------------
Below, these AClights are mounted to wooden 2x4"boards (or maybe 2x6") and layed onthe flat deckin the front of the boat. When it's time to trailer-up, they unplug and get tossed in the truck.



---------------------
This shows the typical light output from a 12volt DC lighting rig. As you can see, it's quite a bit less than the 120v AC / generator system above, but it works, and it'll get you fishing at night. Works best in clear water since they don't penetrate very deep.





Good luck.
