They work!!! I’m going to give a rundown in case anyone else has some issues. What I did wrong was assume a positive and negative based on the color of the wires. I took Sightfish’s advice and took one of the lights off my trailer and put the wires to a common 9 volt battery. By doing this I learned the white is the positive wire and black is ground. This let me know I did need to ground these new lights. The old ones did not need to be grounded. Now that I learned white is positive I ran the power to the starboard light. I then ran a wire to the white on the port light. I took the black wires and grounded them to the bolt that holds the light to the mounting frame for the light on the trailer.
A big thank you to everyone for giving me ideas and helping out. I made a lot of extra work for myself by assuming the new lights would work just like the old rectangular lights. Once I slowed down and thought things through it was an easy job. One more thing I would do is put the boat in the water and do this work without the boat on the trailer. This will prevent you from rolling around on a dirty garage floor.
