Default Re: Installed my HIDs last night

I know this is a very old thread but I want to make one point RE: the annoying shadow line on the road. H7 bulbs can be used in both low and high beam reflectors the only difference is the orientation of the bulb. Tab up or tab down. If you look very close the filament of the bulb is slightly off centerline so when it's used as a low beam the bulb orientation keeps the beam pattern slightly lower than if it were in the high beam housing inverted allowing a slightly higher beam pattern.

Having said that, if you install a HID kit in the low beam housing and see the annoying shadow line on the road the bulb is in the wrong housing. Meaning, the HID bulb in the low beam is really a high beam HID bulb because of the wire placement. Move that bulb to the high beam housing and the annoying shadow line on the road goes away because the bulb is now inverted. Now you need to order the opposite style bulb for the low beam housing.




See the placement of the wire in relation to the tab?
