Just get the lens caps. They're like $60 and snap on. If the law gives you a hard time, pop them off go about your business. The tint you can buy online, especially eBay and Amazon is garbage. I've tried it. $40 I'll never get back. Spray tinting will give you a better look if you do it right, and remove the headlights completely first, but it's an ass pain to remove and takes more time.
