I have installed a set of H1 PnP 8k kit into my prelude. But the bulbs didnt really stay in place because the HID bulbs plastic back piece was shorter than the stock halogen bulb and the metal retaining clip couldn't press firmly against the back of the bulb to firmly keep the bulb in place.
I rigged something up to keep in place. After a while I didn't like the 8k look and bought a set of 6K bulbs and the same thing.
I know you guys must have run into a similar problem with other cars. Anyone got a legimate fix for it?
