I bought fog light kits from the same seller as themerchant for about $79~ at the time
- Bulb did not perfectly fit the foglight housing
- the "plug" from the car's OEM socket to connect to the ballast was 2 wires, had to DIY it myself with lots of electrical tape.
- One of the bulbs burned out within 5 months.
Then I bought 2 sets of 6000k HID bulb-only for $25 a set on ebay from "zgperformance"
- bulbs are a perfect fit. locks on to the fog/headlamp housing just right
- looks good, been on the car for about a month now, no problems.
hope that helps
