like nkn said, pivot controller (about $70 new) or getto rig (about $5 bucks of accessories but you have to be good at timing if you time it).
It will only be "not legal" if you getto rig it where the headlights do not come up all the way (cutting wire/sensor to power motor or disconnecting). A cop could right you for broken/malfunctioning/ or improperly aimed headlights and it is a hazard on the road to drive like that.
Otherwise, you'll be fine.
Tint depends state to states. I believe it is like 5%-15% front windows in California now, or maybe even not at all. Of course, they don't usually pull you over unless you did something else wrong
