LED headlights?
A relay kit and $15 GE nighthawks will do wonders for our old cars. I've picked up the headlights for as little as $5 each on sale.
I don't like the look of LED lights and just because something is "brighter" doesn't mean it works in a range that your eye will pick up. There are a lot of LED lights out there that are not very good, so pick carefully if you go that route.
Pick your parts, pay your money.
