Thanks for clarifying that. I was sure I had full running lights after dark but it was always tough to be positive while sitting in the driver's seat.

I've put a 13'6" rig under a 12' bridge at 70 Mph, but I still don't think I'll try it again.

The system is designed to turn the rear facing lights on at night, it has to pretty dark before they come on.

I've been pulled over twice for other reasons while towing; never a mention.

I look at it this way, it's a mag mount, hit a substantial bump and it may let go, hit the road rip off and then turn into a flying missile that could hit someone or cause them to try and avoid it and end up going into the rhubarb. Is it worth it. Just an observation.

Word of advice. don't turn your light switch to AUTO. Your tail light and marker lights will not come on, even in a heavy rain or snow you are INVISIBLE to EVERYTHING behind you.

On a GM, "auto mode" turns on all your lights - same as if you turned them on manually. This goes back at least as far as the 2000 Impala, my 2010 impala was the same, likewise my 2018 Silverado.

As far as trailer lights being a pain - doesn't everyone own and know how to use a multi-meter - well everyone over 30.

I find boat wiring (lights, live well, fishfinder) to have more problems than trailers.

Has anyone else switched to LEDs ? I did and haven't had any bulb issues since. They run cool and don't pop when they hit cold water. I still unplug anyway. Remember to use dielectric grease before installing them.

All about dielectric grease. Apply it after connections are made, not before. It's actually an insulator.
Dielectric grease, or tune-up grease, is a silicone-based grease that repels moisture and protects electrical connections against corrosion. ... The grease does not conduct electricity, so it shouldn't be applied directly to the mating surfaces (pins and sockets) of an electrical connection.

You sure about that? Auto mode means they come on automatic when the photocell signals its dark enough. On is on whenever.
Sorry thought this was a current post did not look at the date.
