I have wire frame items for Christmas time (Santa sleigh/2 reindeer/2 angels) that are currently wired with external use LED lights (100 ct string increments). The figures are decent size so I would need a more spread out density NOT CLOSE DENSITY and they have to be able to link between units for connecting electricity and run on a timer. I was thinking of doing something programmable so that I can do the santa in red with white gloves, as an example. I do need waterproof (I live in FL so it definitely rains, and at least one good hard thunderstorm around Christmas). Obviously cost needs to remain decent as I have multiple pieces to work on. What's my best plan?
