It's just a "Jones" / "Fad" thing. It used to be car alarms, thank God that's over, I used to say, "I wish someone would steal that car so I don't have to be irritated by that &%#$ car alarm anymore" LOL.
Then all the kids had to have those low profile touring tires, which cost $2-300 each and last about 4 months, then it was car stereos that went BOOM, BOOM, and basically that was just a expensive way to shake the rust of their moms old Buick, and prove how worn out their old rattle bucket actually was.
Now about these irritating blue light bulbs, why? You can't see any better with the things and they appear to "wash" out what's in front of you anyway. The human eye is not designed to see with that color light, if it were, headlights would have been made differently eons ago.
But, anyway, as far as the tint thing is concerned, it's illegal anyway you look at it, it's a safety issue both for law enforcement and vehicle operation. So, if you wanna pay the money and enjoy it while you have before you get the ticket to have it removed, go ahead. But, why not just save that money and put gas in the tank.
