As the former largest importer of xenon lighting to the US (sold the business last summer) I can tell you McCullah and all the other junk on eBay is garbage. I'm too tired to go into specifics but do yourself the favor and get a set of litronics for about $1,000 brand new. Best upgrade you can make. You drive a Porsche, not a Honda Civic. Please don't retrofit with Taiwan made junk. Thanks.
