Right Rear Taillight - Illuminated on AC

[Ralph Mawyer]

This seems to be a weird one. 
 

Any idea why my right rear taillight is illuminated while on shower power. 
 

I did unplug and reconnected and it was off, but is back on now.

Sometimes moisture/water in the trailer side of the 7 way plug will cause phantom light issues.  It is worth looking at.  I always hang my plug with the plug-in connection pointing down to prevent moisture problems.

Been raining for two+ days. Covered it earlier, but did have some corrosion starting to develop.  Cleaned contacts and all is well. Thanks.
