Each year they are getting better and better. Better cooling options, better dispersion and control, better brightness, and lower cost. I like the ones (headlights) I have now, although they could be a little brighter. But just a year prior to those, the models were worse and more expensive. I just think they have hit the sweet spot in the last year of being at least as good as halogen and yet affordable, too.
Now, in 5+ years, the designs will probably peak and then the prices and selection will start getting worse. Why? Because the market will be saturated and the vehicles that can use halogen bulbs will be far fewer (because new vehicles will all use factory LED).
