My little HF trailer I use for general hauling has been hit from behind 3 times.
I believe the lights are too low and hard to see.
That isn't easily fixed. (although I did upgrade to LEDs which is a huge improvement in light output)
However, for my tear build, I want as much lighting as possible on this beast.
So, is there a guideline for what you can and can't do to illuminate your trailer/camper?
I saw one post where someone put a third brake light on their unit and I plan to do that.
I also plan to move the brake/tail lights onto the back hatch and off the side trailer mounts.
How about additional running lights? What's allowed?
