I have the cables from 9 bulbs joined into one using a screw terminal temporarily. What is the best thing to use to do this in a way that's waterproof and suitable for outdoor use. Whatever i use needs to be small and black, and fit on the back of a branch. I know the bulbs are over rated for the dimmer, i guess you can go over the max rating somewhat without that much of a risk of fire.
and this is the decroded piece of crap i am working on in its entirity...
