Hi,
The reason for the ones I suggested is that you have just the LEDs with an included suitable resistor inside the LED.
Each LED can be chosen with a short 2 wire lead of red and black.
You have to extend , as necessary , the red wire of each LED to a switch, then to a fuse and then to the battery positive terminal.
All the black wires are joined together and taken to the battery negative terminal.
2 whites , a red and green LED will give you the minimum tug lighting of a steaming light, stern light and port and starboard lights.
There are other combinations of lights required for certain jobs.
These can be arranged and turned on by another switch, fed through the same fuse.
A fuse of 2 amps will be more enough to drive many of these LEDs
Is that more helpful to you?
Just ask if you want more.
