Got a bit bored and needed a quick, cheap project. $20 at Home Depot and and old PC power cord (I liked this one because it was really long) and I had myself a tacky light dimmer.
Because I got the cheapest dimmer in the store, I find it works best if the lights are plugged in, then plug the dimmer box into the trailer. I guess the dimmer thingy doesn't like to be unloaded.
I got the weather resistant box to put it in, and sealed a bit with silicone, but I don't think for a minute the device is outdoor rated.
Wiring the thing up should be fairly obvious to members of this form. If you don't know how to wire up a duplex outlet, pick up any home improvement book and read the directions, or get someone to help you. Miswired this could be a dangerous thing.
What is lacking is a way to mount the thing on the awning arm, but I'm leaning towards velcro straps or something along that line.
No more blinding awning lights...so romantic, just me and the wife...
