If it were me I would rig a tail light, brake light and florescent red flag to the end of your PA on the rear carry rail. You know the lights like the ones the tow trucks attach to the wrecks that they tow. You can find this at Harbor Freight for around $20.00 item#69626
Technically your rig is not legal in Calif, because you have too much overhang behind your lights.
Just because you have not been stopped yet don't assume your legal.

This might help. This is only for Calif. I can't give you any info on what Mexico traffic laws might be but in Calif the California Department of Transportation states:
"[...] whenever the load upon any vehicle extends, or whenever any integral part of any vehicle projects, to the rear four feet or more beyond the rear of the vehicle, as measured from the taillamps, there shall be displayed at the extreme end of the load or projecting part of the vehicle:
a solid red or fluorescent orange flag or cloth not less than 12 inches square, or
during darkness, in addition to the required taillamp, two red lights with a bulb rated not in excess of six candlepower plainly visible from a distance of at least 500 feet to the sides and rear."

As for the length of overhang per California Vehicle Code Section 35410, "the load upon a vehicle, trailer or semitrailer shall not extend to the rear beyond the last point of support for a greater distance than that equal to two-thirds of the length of the wheelbase."

I hope this helps, if nothing else it will give you peace of mind while driving in Calif
