Trailer lights question

Trailers are a mystery for sure. I had a trailer that was getting old got the lights all working, then decided to under coat the trailer with the no drip stuff. Lights never worked again. Had to run a ground wire to each light to get them to work again. Somehow the undercoat stopped the ground through the trailer.

Yeah! Voodoo for sure.

My Gmc Sierra also has the auto lights but there is a switch that overrides it and you can turn on your lights whenever you want.

Today,I went to Canadian Tire and bought new LED trailer lights. I wired them up tonight and grounded each light pod to the trailer with a separate lead. They work perfectly,four ways,signals,brakes,side markers (which haven't worked in years) all of them. I'm a happy camper. Trailer lights are the spawn of Satan.

9 out 10 times bad grounds are the problem with trailer lights. I remember back when they used the ground from the hitch/ball contact with the vehicle.

Not really. Theyre both driving concerns.

My point is it would have to be a really slow day for a cop to pull you over and charge you under that offense.

Thinking that is a mistake. OPP and MTO have set up regular inspection stations just for that purpose on Hwy 7/115 and all points north through Peterborough County. It's scary to see what they've found. You just wouldn't believe the stupid shyte people do with unsafe trailers and unsecure loads.

In Auto mode the only lights on a car/truck will be the daytime running lights.

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.

Had a cop(OPP) pull me over as I was making the turn off 17 to 129 north.
Said he'd had a few calls about me weaving and riding the shoulder. There was one car that had been behind me since Spanish River. I said I am sure the guy behind me was the one, cause I was going 90 and he wanted to pass. Said I tried to help him go around by moving over on the long straight sections, but he would not pass.

Cops says that's likely it. He then looks at my License and says" YUP!:rolleyes: ...Knew you had to be a truck driver....ALL the trailer lights are working." ;)

We're talking about properly functioning "portable/emergency" lights. Not a crazy/scary load.

Ive never heard of ayone receiving a charge for having them. I know lots of people that use them.

The above quoted regulation was also a federal law. Thats low on the list of things OPP and MTO are concerned with in a traffic stop.

My truck is always on auto mode. All lights come on when it gets dark enough for the censor to turn them on. I have had them come on during storms as well.....
