The headlights lenses on my 2006 HSE were absolutely horrible. Yellow and spotted up as can be. After trying multiple other systems including Maquire's and Turtle Wax, I found the Sylvania Headlight Restoration Kit. It worked amazingly well. It takes about 20 minutes and a bit of effort sanding but the results were well worth it. I was looking at replacing the lamp assemblies at hundreds of dollars cost but this $20 kit absolutely fixed them.
