Are these bulbs for the low or high beam? Genuine projector headlights use h1 for the low and h7 for the high beam, you should only put HIDs in the projector lens and leave the other as a halogen bulb, that picture above is a h7 bulb (can tell by the tab at the left hand side) and as it's plastic I'd be unhappy with using them but that's just my opinion I have no issues with the quality of HIDS4u products just personal preference, if you look on back of the headlight around the rubber cover that allows you access to the bulb it should tell you which bulb goes in that opening, looking from the back on mine it's on the bottom left hand edge.
