Background is that I purchased a new tow vehicle. Since doing so, my trailer lights flicker rhythmically while the truck is off and it is parked in the lot at the lake. At first, I thought that it would quit after a while due to residual lights in the truck and the super-low voltage threshold needed to fire the LEDs. This is not the case, as it will still be blinking hours later when I return from fishing. For reference, this did not happen on my last tow vehicle.
I know that this is caused by small amounts of voltage building on the truck's trailer wiring, but I'm not sure how to stop it. Is there a fix out there...a resistor kit or something that can be added between the truck and trailer? It's not enough current to drain my truck's battery, but it is a bit annoying.
As I'm sitting here writing this, I'm wondering if it blinks in cadence with the security light on the dash??
