I'm playing the 1.41.1 version of the game (I think that's the latest) and whenever I encounter police I get a fine with the message "headlight offence" and I'm charged about €200 every time. I've tried turning on my lights to the medium/normal brightness and it doesn't work.
There is absolutelly no downside (at least in game) to keep the lowbeams on all all times. Do this, and you'll never have to worry about any headlight offenses. Of course, switch to highbeams when you can't see a damn thing outside, but turn it off when on country roads and with traffic approaching you. #4.

There are arrows on the seat-adjust icon, because the seats can be adjusted from the F4 popup: up, down, forward, and back. There are arrows on the mirror-adjust icon, because the mirrors can be adjusted similarly. There are up-down arrows on the headlights-adjust icon, but they can't be adjusted up or down. They can only be turned on and off.

ATS Headlight Usage Offence. I always drive with the running lights (parking lights? The first notch of the lights anyway, not the low beams and not completely off) on during the day. I haven't played in about a year, and now when I drive in the middle of the day in perfect weather with the running lights on I get fined for Headlight Usage.

The game may not reflect laws on a country by country basis, so what the law is IRL doesn't much matter. Bottom line, keep headlights high or low beam (not parking lights) on 24/7 and just don't worry about it. The "Headlight Usage Offense" is only for not having lights on when required. Any other state is irrelevant. . 166 14 253 412 108 397 462 492
