I think it is a great idea, but I do have one suggestion.
You show the quick coupler mounted on your vehicle facing up. You might want to keep it covered when you are not using it to keep the dirt and moisture out.
Or, swap the male and female ends. I've done this for years with a small fiberglass indicator rod, male is fixed, female mounted on the rod. A threaded nipple in the male end with a galvanized NPT cap to tighten it on the angle iron support keeps it in place. Drill a 1/4" hole in the cap for dirt and dust drain. A plumbing compression sleeve fits the bigbox store fiberglass driveway marking rods, and holds the rod securely. I'm not where I can take a picture of the assembly, but if anyone is interested I could get a couple this evening.
What a great idea for the flag mount on your off road vehicle. Easy on and off .

I used that nifty idea many years ago on a work light. The other half of the coupler is screwed on a pipe, on a stand to hold the light up off of the ground.

Is your light sitting on under ground pipe line pipe? Looks like what they ran through my property. They took all the scraps with them![]()
