    FFS I just cancelled my LED order from Amazon. I don’t need a bunch of electrical issues on a new truck.

    Possibly the third brake light leaking?
    Any light stains/discoloration in the rear of the headliner?

    That was my first thought. I checked and found nothing. My next plan is to run water on each suspect spot (third brake light, fin, door jams), eliminating each until I find the culprit.

    Exactly, led stands for light emmitting diode. A diode allows current to flow in one direction so they only work in one orientation. Some fancier ones have crossover circuits that allow either orientation while still allowing current to only flow the correct way through the led(s). It is still possible to have a short in a lamp assembly but even then if a fuse blows and a problem crops up elsewhere the problem is bad engineering since the fuse is proven inadequate to isolate a surge.

    This is why I cancelled this upgrade.

    I'm in the same boat here. Lights stay on. Truck is under warranty. I put the stock bulbs back in. Going to take it to dealership next week. What did you "tell them" how the problem started occurring? Thanks!

    I just installed LED’s in mine and ran into the same problem. The map lights are designed so that you can push the lenses to turn them on and off. Sometimes when installing the LED’s you accidentally push the switch to the on position. The switch is located in the recess near where the bulbs go. It’s a little black protrusion in a hole. All you have to do is push on it again with the tip of a pen or pencil or something to reset it back to the off position. People are way overthinking this.

    The problem I’m having with mine is that the LED’s don’t fit the brass base designed for the halogen bulbs very well. I can only get one side to stay on very long because it doesn’t make a solid contact.

    Led’s are and bright and nice to have if you can get them to work correctly. But they are a pain in the ass if they don’t.
