I've been looking at getting some windshield mount brackets for driving lights for my Jeep, and was just looking over the Iowa laws for them on this site. Iowa Lift Laws | Vehicle Modification Rules
According to this, the max height at which you can mount them is 42 inches. The windshield mounts would be approximately 52 inches.
I know some of you out there have the windshield mounted lights, and was just wondering if they police have ever given you any trouble about them being too high up?
