I’m in much the same place with an ‘06. First, are the lenses nice and clear or yellowed? Easy DIY with a kit to get them clear again.
Halogen bulbs deteriorate over time so maybe get a new set of whatever is in place. Or, there maybe some upgrades worth a look at.
I used ring 5000k bulbs on my nc3 and they’re a great improvement. As already said, if your lenses are hazed I’d start with those first but the bulb upgrade was well worth it.
