Like moodfood said you might want to run coast guard approved lights, it will just give you one less reason to get stopped. By law the lights have to have coast guard approval markings on the light. (just went through that on one of our boats down here the lights can look right but without the markings on the lights they are not legal)
You might want to try to look at

You can look online and see if they have anything that will work for you and then you can either order from them or at least go somewhere else and order them.
Just for information, the running lights on a boat are to be viewed as follows.
Red light goes on the left side of the boat when looking forward(port side). It should only be viewed from forward midline of the boat arround 112.5 degrees which would be just behind midships.(90 degrees)
Likewise the green goes on the right side of the boat facing forward (starboard side) and shines the same 112.5 degrees. The reason for this is you are only to see the red or the green light on the vessel not both together unless the boat is coming directly at you. You should not be able to see the red or green when aprocahing from the rear only the white stern light. On vessels under 40' you only need a white all around light
as a stern/masthead light that can be used as a anchor light also.
If I can help out at all on what is legal as far as lights just let me know.
Mood : Led lights are great and they do have some that are approved but they are VERY sensitive to voltage. I dont know if that is the problem Larry was having but it would be a good guess.
