Hello. I'm new here but I'm in a bind. I had to leave my 2014 Mobile Suites Estates behind for a family emergency. It is plugged in and set up. I just received a call from a friend at the campground. My warning lights on the 5th wheel are flashing and the brake lights are on. It is not hooked up to the tow vehicle. Can anyone think what is causing this? My friends have access to a set of keys I left hidden. I had my friend just try disconnecting from power, check breakers etc, but the are still flashing. This friend unfortunately has very little knowledge of RV's.

Sounds like something shorted out in your pigtail, did it get wet?Have them disconnect the batteries. Someone at the campground will know how to do that.

Don't understand the "flash", since there is not a flasher in any trailer.But a shorted pig-tail would be my best guess also.Disconnecting the battery will NOT fix that, as the power from the converter will still be supply 12VDC

By warning lights are you talking about the running lights? And the brake lights are solid illuminated? Is the flashing intermitant or rhythmic? By hooked up are you meaning you are attached to 120 v shore power?At worse remove the bulbs. Jim

Hope everything is okay at home. The lights are probably not your main concern about now.....

First thing I would ask my friend check. See if someone placed a flasher relay into the end of the pigtail that connects to the truck. Seen gremlins at campgrounds doing this for fun.

No bulbs to remove as all lights are hard wired LED modules.
I agree that pigtail (plug that plugs into the truck) would be the only way voltage would get to running/brake lights. If it is wet or in water the 12vbattery charge terminal is backfeeding to the taillights.

Disconnect the battery, and shore power...sounds like a circuit breaker is cycling, causing the flashing lights, Unless someone has put a flasher in the pigtail as a prank.

Your DRV, like ours, probably has a remote that has key fob with a panic function that will flash the lights that is hooked up to a module in the coat closet by the front door. We had some issues when ours was new and have not used it. You can probably unplug the module--its called the "wow" module to stop the flashing if you do not have the remote available. Hope that helps.
It also controls the scare lights, slides, awning etc.

Hope that helps!
