Sorry Jeff, the blue light is not on the barge/ tow,
I thought is was a "gun sight" to help steering, not for others to see.


well you thought wrong.
and you failed to
mention why a blue light is required in addition to regular towing
lights.
You didn't ask what it was for, only what it was. In knowing what is is you will know what is is for.


Of course, it could just be the Dog Star.

Could be uranus...but neither are running lights and not likely to be
mistaked as one another.

Now put on your Dunce hat and go sit in the corner with Charlie.

"A steering light is a small blue light installed on a pole placed on
the centerline at the head of the tow facing aft. The operator may use
the light to detect heading changes and to align the tow with respect
to a bridge or other restricted navigation area during periods of
darkness."

And now you claiming its a "running light." I'm beginning to think
its just some idiot Texan who puts Christmas lights on his boat.
