I've been in many boats with tower lights, own a pair myself, and I still sustain that they are completely useless except for wakesurfing & docking in the twilight. They actually make it more difficult to drive at night... they reflect off every inch of fiberglass, making it impossible
to see past the bow.
All the companies that make light bars use essentially the same lights - driving foglights, which are pointless for our application. I've found the best solution for night-riding are these:
Below the rubrail, so there's no glare. Mastercraft made a nice adaptation this year - they are producing their tower lights with a "shroud" to prevent light from dispersing at such a wide angle.
My recommendation: save the money and invest on something else. If you do, you'll likely ask yourself "why did I spend $650 on these things???"
