I think my last response didn't get sent but here it is again for you. Its a combo of both headlights and height.
NHP will have a field day with your truck. I'm sure of it. I can bet that a normal city/sheriff won't care but NHP sure will.
It would be a fix it ticket I believe. But what a PITA to have to remove your lift and get it inspected and then put it back on.
Here are the NRS's you need. I'm sure your truck whatever its weight is taller then 32" from the lowest portion of the BODY.
