I wanted the look of "blue flames" at night coming from my outboard. When I received them, I was a little skeptical as they are not very big. But boy was I wrong. The light up the "rooster tail" perfectly. It was the exact look I was hoping for. They are very bright and look amazing. I wish I could post pics on here to show how well they work. Super easy to install. I installed them on my Minn Kota Talons.
