Headlight laws?

I don't know where you live at, but in Ohio we have random traffic checks and the State Patrol will pull a line of cars over and give them a safety check. They check your turn signals, tires, horn, tires, lights and give the vehicle a visual inspection. If it passes, they give you a window sticker and they won't stop you again. One of the things they check for with your lights is that they all work...including the high beams. If they do not work, you would be issued a fix-it ticket and have 3 days to get it fixed, or you would get fined, or more. You have to prove to them that you actually had it fixed. I live in the countryside, I can't imagine driving without having the option of high-beams.

In Illinois, as in most states I am sure, you must have 2 working low-beam headlights. High beams I am not sure about but for safety reasons and relatively cheap costs, why not replace them?
