What would cause my running lights not to work but my turn signals and brake lights work?

Those are two different circuits
Fuse in vehicle, Or bad connection on the brown wire between the plug and lights.

Or an open filament in the bulbs.
What are the odds of ~10 light bulbs failing at the same time?Originally Posted by Alex from GA
If you have integrity, nothing else matters. If you don't have integrity,
nothing else matters.
Just went thru this same thing. Check your fuses and relay for trailer parking lights in your truck. Then check the plug coming out of your truck with test light to ensure your getting power to your trailer light pin. I did all this and mine ended up just being a bad trailer ground. Just had to tighten the ground screw on the trailer. ��
No... These are wired parallel and the filament has no effect.

If the ground was the issue, None of his lights would work...

Not true. I had brake lights and turn signals. But no parking lights. Had a ground screw that needed retightened that bolted on the trailer. Soon as I did that she lit up. After 4 days of trying everything else. Different circuits are grounded on different points of my trailer.
Yes, but just as all roads lead to Rome, all trailer lights depend on the frame for ground which should be grounded by the white wire. Turn signal and brake lights have an obscure remote chance of carrying enough current to "burn through" corrosion on a bad ground, but not likely.
Some run a white wire to each light for a ground, but not many.
For any trailer light issue, start at the connection between the truck and boat. Check if you have 12v to the non-working lights at your truck connection. By starting there you either eliminate the truck as the issue or identify the truck as the issue, either way you remove 50% or so of your "educated guesses" after that.
Everyone should buy these to keep in their tool box. This would eliminate half the potential issues in 30 seconds https://www.amazon.com/IIT-16687-Bla.../dp/B008L2WFMU
Right. Too bad it doesn't have a 5th pin for the back up system, but it will still check the others.
it will check backup lights, reverse lights and 12v aux power. as well as running, turn signal and brakes
I see what you're saying but I only see 3 positive male pins. It might work off a different theory than my old fashioned straight wire training. There is however, a different one listed which might have functions closer to my understanding with 4 male pins: https://www.amazon.com/ONLINE-LED-ST...7PR1WGZ8K0RX1B
Great find... I ordered one here... 5-Pin Flat Trailer Wiring Tester for Light Wire Circuit Continuity Test | eBay

Hook up to a friends truck. If the running lights work, it’s your truck. If they’re still off, it’s the trailer. Likely it’s a fuse in your truck.
There is a 7 pin round connector on the other end.
