I threw mine out after they failed last year, water got into the white control box.
What about mounting the white control box inside the orange plastic done where the porch light is? Take the bulb out, fashion a tap or take the end off and use the leads to power the white control box with DC, then a lead out to the strip mounted on the side of the trailer under the canopy?
