Thinking about running 1/2" pvc down left side, coming up at light locations into a 7 hole wp 2 gang box, coming back out of 2 gang up to a round wp box for fixture, back out of 2 gang for fixture on opposite side under dock, (hope there's no snakes) 90 ing up to fixture on other side.(Trying to keep most of the conduit where it's not seen as you approach the walkway). Still don't know exactly how I'm going to strap it horizontally though, unless I add some kind of support between the pilings.
