Is this a direct "plug and play"? How was the installation?I used HID bulbs from Xenonlink.com for many years on my Harley Road Glide until I switched to LED head lamps. I can highly recommend them. Check these out for the truck: XenonLink.com HID Conversion Kit. 9006 6000K Automobile HID Kit
Stick with the 6000k color for the whitest / brightest.
Yes, it is plug and play. You must secure the ballasts to some surface. Use either velcro or 3M double stick tape. I prefer velcro in case you ever need to move or change a ballast. Should not take more than a few minutes. I have not installed a set in a truck but have installed several sets into Harleys for myself and friends. They are nearly as good as the newer (and far more $$$), LED head lamps.Is this a direct "plug and play"? How was the installation?
