Trailer light issues

[Ajdarling]

Just bought a 25' Ram 2500, My 2 work trailers that are both less then 3 years old with LED lighting work perfectly. My older boat trailer with incandescent bulbs wouldn't work so I switched all the lights to LED. Now everything works but when the truck is not moving all the trailer lights flash on and off every couple seconds, not flickering but flashing like they're on a sequence. As soon as I start driving they stay on. I rewired the whole trailer, grounds are all clean and new. Anyone know what is going on? Thanks in advance for any help!

You might try over on the sister site hdrams.com where the 4.5gen HD folks hang out. this is the 5thgen (1500) site.

Seems to be an issue on the 25's and many have had TBM and other parts replaced to resolve, though the sequence flashing sounds new. Perhaps it's running the trailer light check that nobody seems to be able to trigger. Best to see your dealer for this one.
