How many and at what locations do you have marker lights on your build? What size is your trailer? Orange or red marker lights? Using any reflectors rather than lights?
My travel trailer is 6 feet x 10 feet and 6 feet high. Right now I have 2 orange led lights for the lower front sides, 2 red led lights for the upper back sides and tail lights that also have lights on their sides. I have 4 orange reflectors that I plan to attach around the top. I also plan to use a third brake light.
I sometimes see trailers with a LOT of lights all over them. I wonder if I'm doing enough.
