In TX, it seems to be a the culture that you turn ‘em on and leave ‘em on wherever you go. Downtown, uptown, out of town, in the sticks or where the busses don’t run. If you have a Jeep, or Super Duty, it’s legal immunity from any charge for non SAE lights.
Seriously - I’ve seen 1 each Jeep and S/D literally blaring off roads into an oncoming LEO vehicle ... and everyone else. One of them was at an intersection, stopped at a red light at night turning night into day. Neither had any trouble and none of the lifted super duty’s around me have any compunction about lighting up oncoming traffic.
I don’t use any more than the SAE if there’s oncoming traffic
