How are the HID bulbs supposed to be oriented once they're finally installed in the car? There's a metal strip looking thing running the length of the bulb. Is that metal strip supposed to be on the bottom, top, or side of the bulb itself once it's installed? I haven't installed mine yet, but from looking at the pics on Visualdynamics website, it looks like the bulb can be installed into the adapter housing in any of 4 different ways. Thanks in advance.

 

It doesn't matter. THe just need to be inside the headlight housing
