Dan, I've seen them chromed in Baltimore City. Any chrome shop will do it for you. Call up your local car restorer shop and they can put you in contact with a local chrome shop that'll chrome plate it for you. It'll be costly though.
If it was just the lines under the lights, I think it would look okay, but the whole piece will look a bit too shiny. And if your car color is dark the contract from the hood may give it an odd look.
But to each his/her own. If you do it, please post pictures!
Cheers, Sean
