I had very foggy headlights in my 2007 Chevy Express...tried the polish kit and still bad....so replace? called chevy..they wanted $235 EACH for the headlight component that comes out with 2 bolts....soooo lets try Amazon ...I found a PAIR of headlights for $72 with free shipping...yes from china but brand new WITH new bulbs....OEM on the will packed box...and you can't tell the difference in the old from new gasket look the same ...same weight looks like GM has their headlights made in china...20 minutes later new headlights....
