    The previous guys are probably right regarding the extra socket.

    Are you confusing Halogen lighting with HID lighting? Halogen light bulbs have a filament that is similar to a standard incandescent bulb. The glass is smaller and is made of quartz to withstand the temperature. The bulb is filled with halogen and allows more power to be applied across the filament. The resulting glow (measured in degrees kelvin) is a whiter light, usually about 3000K. Most cars have halogen bulbs. The temperature is a measure of the color of the light.

    HID lighting (high intensity discharge) is a bulb that uses an arc discharge across a gas inside a quartz envelope. The temperature is in excess of 5000K. HID lamps require a transformer to provide a higher voltage to jump the arc, kinda similar to a fluorescent light....but different chemistry. HID lamps require less power, have brighter and whiter light and cost much more. The gas is a metallic like metal halide, mercury vapor, or sodium.

    The Fake HID lamps use some colored bulb but are junk...sold at the sucker counter at Pep Boys and such.
    If it doesnt have a transformer, it cannot be HID.
