I had a look at the ebay add, they state fog lights in the description and spot lights in the techical detail. I find errors like that bring up warning flags in my mind.
I like HID better, lower power, more light. Apparrently LED is getting much better too. My HID driving lights are 4 inch reflectors, 1 flood, 1 spot with ballasts built in. They are a chinese brand and have been fine.
