Sorry it's taken me so long to get back to this. Things have been busy here.
I want to hang this box below some duct work in a pedestrian aisle at a point where there is poor visibility of approaching forklift cross traffic. I will then mount a micro-strobe and annunciator on the bottom edge and apply an adhesive label to the front and back of the box that says "Forklift approaching" The stobe and annunciator will be triggered by existing sensors to warn pedestrians of approaching forklifts (who's drivers can't see past their load)
