Height of front facing lights varies per state.
In my state, you are limited to six front facing lights no higher than 24 inches from roadway surface.
Six sounds like a lot but when you consider mid-late 90's model vehicle often had a set of dims and set of brights, you could only add two additional light heads.
Now, this was not limited to off road vehicles. The roll bar and limitations were different, when I first started copping the any top mounted forward facing light were limited to five. Then it changed to six and then they added mid level lights for crawlers or mudders. Mid level are hood level, such as spotlights or handheld lights.
One of the biggest and easiest offered way back in the early 00's were dodge and GMC pick up trucks. The dual headlight assemblies with optional fog lights hit the limit, putting a grille guard or extended bumper with a pair of driving lights could have been an automatic citation. A cheap reason for a bored bacon to stop and say hello on a tuesday evening.
Anyway, sorry that doesnt matter for this post.
You need to check with your local highway agency or local PD.
They could give you the exact yes or no you need.
Also, a shortcut is telling anyone who may have a legal issue with the additional lights that you only use them when parked and not while driving.
I always assumed having floods in the flashers would be horrible for driving with such a spray and light wash on the hood would be more blinding than illuminating.
Either way, I would like to see how they turn out.
