It's common for tail/brake lights and clearance and marker lights not to be LED's at this point in time. Those lights only operate when the trailer is plugged in to your vehicle and presumably when the engine is running.
What boggled me was that every light in the trailer is LED, the awning light is LED the light on the power jack on the hitch is LED, yet the light under the steps (not all are equipped with this light), the back drivers side corner light (spook light above the outdoor shower; again not all are equipped with this), the light mounted on the outside front wall by the propane tanks, and the light in the hood fan above the stove were all incandescent bulbs. I have since changed every light which runs on the trailers battery system over to LED. My clearance, marker and tail lights are still standard bulbs since they do not run on the trailers 12 volt system.
