Finally got my lights today, going to install them in the morning. I already have HID's to put in but I'm going to use them for a week with the bulbs that come with them. They are simply plug and play but they also came with a separate wiring harness, not sure exactly what it's for though.

 

ballast?

 

Did some searching and it seems it just a extra relay harness but its not needed.

 

Just installed them this morning and taking your front bumper off for the first time was a bit of work lol. But now it will be easy since I know exactly what tabs I need to remove. The lights fit perfectly, exactly how the stock lights do.
