I searched but did not find much. Who sells aftermarket headlights (stock look)? And how hard are they to replace? I see some on Ebay but not sure of the quality.
Mine are looking kinda hazy.

 

They have restoration kits that can make them looks good as new again, and it'll save you $500 for aftermarket headlights. Unique Style Racing sells aftermarket headlights for our cars. Or you could they this restoration kits.

This is the one I'll be going with this summer, heard a lot of good things.
