Deck and stairs lighting

Struggling with finding the right low voltage lighting solution for my stairs down to the lake, I printed this little unit which uses a T10 wedge type LED bulb (you can find a bunch of 12v types off of Ebay). I printed out of ABS it screws to the side of a deck or stairs. The back is open, so I recommend putting a piece of electrical tape over the hole in the back and hot glue over the leads coming out of the side to give a fairly good seal on the back.
