I have an ebay kit. I installed the low beams with the bulbs they came with. Not much of an improvement. They are glass however. I am waiting to buy another pair of Kensun HIDs, so I can convert all headlights of the headlights to these with HIDs. The reason is that the HID pair uses a single H4 connectors. I want to wire it all at once.
As was mentioned above, you will need to cut into the headlight housing bracket to make these fit. I also had to cut into the headlight itself because it was hitting something behind the headlight housing.
