I'll be travelling to Cal. a week from now to visit my sister, who shops at Costco often. So I'm wondering if they still have the HID for sale there?.. If so, and I find one...
I believe that Costco only carried them for a short time as they were testing the market for them. The manufacturer has since redesigned the lamp a bit and is now providing them to Harbor Freight tools instead of Costco. And only via mailorder.
