Legal tint on windshield texas

Hey y'all, looking to diy some tint on my ls430, I got a lower value for the windows and a choice of 50 and 75 on the front windshield all ceramic. But when with 75 I'm worried about getting pulled over with it. And I don't want to pay like 300 bucks for the full clear ceramic tint in a shop if I could do it for cheap. Anyone rocking these in Texas, Houston?
