Besides EBAY, are there any reputable sites to get a replacement Headlight Assembly for my 2011 es350 I checked EBAY and the headlight assemblies I seen for the 2010-2012 didn't all appear to be the same at all for HID. Some of the headlights labeled 2010-2012 seems to have the connections for the 2007-2009 which leads me to believed that is incorrect. Any help is appreciated!!!

 

If you want used, try a site like car-part.com to search salvage yards by distance from you

 

Well there were both Halogen and HID headlights offered on the ES. You were probably seeing both and possibly some stuff not identified correctly.

Try this used Lexus parts yard. http://www.rancholexusrecycling.com/

Since you are in Maryland, try Brandywine Auto Parts as they are the largest in Maryland, mostly in Prince Georges County, with several yards.
