Can anyone answer why one of my low beam HID's (pas side) goes out when I turn the high beams on? 95% of the time it goes off,once in a while it stays on. Thanks,CHRIS.....:confused:

How do you have your HIDs wired? If they are connected to the factory switched grounds in the OE headlight wiring that is your problem. When you switch between low/high beams using the headlight switch the ground to the headlight is momentarily interrupted. This has no effect on halogen bulbs, but will cause HID ballasts to flicker and/or shut off, requiring a power cycling of several seconds off and then on to turn the lights back on.
The best way to avoid this (and the best way to wire the HIDs overall) is to move the ballast negative connections from the switched grounds to a direct ground, either at the chassis or the battery negative terminal. When grounded this way, the HIDs will come on whenever the headlight common power is on regardless of low/high beam mode, and won't be affected at all by switching your high beams on or off. Just be sure your DRL module is disconnected.

Thanks, I know that the drl's are disconnected, had that problem already. As far as the ground goes I thought it was conected to the battery I'll double check. They were installed by the body shop after my acccident. CHRIS......

When I installed HID highs I was having a problem with only one turning on at a time, and it would switch back and fourth. Sometimes they would both work but they would short out when I drove a little. I found out that the metal on the ballast could not touch the chassis at all. I guess they made the HID ballasts (+). This struck me as odd since the directions mentioned that you could screw it in for mounting. The ballast was made by Eagleye. Hopefully this helps someone, because maybe this has happened to one of you.

By the way, to fix this you can put something like a thick sticky pad between the ballast and the chassis, and use the holes to zip tie it down to something under the hood. Just make sure there is no contact between the chassis and the ballast.

I figured out this problem. I had my battery replaced under warranty and when the new battery was installed the problem went away. Must have been a loose ground at the battery terminal. CHRIS.....

anyone have a wiring diagram of the setup as stated above w/ low beam projector and high beam projector setup to to have both high and low on w/ high? if that makes sense

With Morettes there is no wiring required, they are made to operate that way.
