Our 2500TS came equipped with a row of LED lights tucked under the awning. On our last outing for the season, we were camped very near to the lake shore. Our daughter-in-law was experiencing her first trip in a MH and our son was more than thrilled to expand his memories of growing up camping. The LED lights were on while we enjoyed an evening campfire.
It was very dark when our camping neighbors returned on their pontoon from dinner across the lake . We had a great conversation with them after they told us our LEDs had been a beacon for them to find the campgrounds.We never thought of it that way.
I ran this some of the conduit below along the frame ( used existing screws holding coroplast using cable clamps) from the tongue to bumper. I ran a tracer line in it. I used it to add back up lights and B/U camera wiring). No advantages to AC lights as if you have AC, you are not using battery anyway. All LEDs are DC as mentioned above.
