Headlight retrofitting (Retrofit 201)

Projector retrofits come in many flavors. The most common  setup is the single xenon setup, in which vehicles with  separate low and high beam bulbs have their low beam  reflectors retrofitted with a single xenon projector such as the  RX330 and S2000 projectors. When vehicles come equipped  with dual filament bulbs, i.e., 9007 and 9003, there is a choice  between a single xenon or a bi-xenon projector retrofit;  although, the latter is recommended. A bi-xenon projector (see video on the right) consists of one  projector with a motor, or solenoid, which upon activation  alters the light output to convert the projector from low beams  to high beams.
Dual Setup A dual setup is a retrofit where single xenon projectors are retrofitted into the low beam reflector, while a set of halogen projectors are  placed in the high-beam area. Usually, the halogen projectors are retrofitted up-side-down, to overlap its cutoff with the cutoff of the low  beam projectors. Retrofitting the projectors as such ensures functional high beams. Quad Setup Similar to the dual setup, yet very different, is the quad setup. From the latin word ‘quad’; meaning four, the quad setup consists of four  projectors that are activated when the headlights are on. Most quad setups utilize a set of single xenons together with bi-xenons, OR  two sets of bi-xenons. Despite the increased amount of light, when retrofitted correctly, and aimed properly, the only difference from a  single xenon setup is the amount of increased foreground lighting. The quad setup is one of the more expensive projects, since it  requires two sets of ballasts, bulbs, projectors, shrouds and wire harnesses.
HID Projectors Projectors are the primary component of the retrofit, and there are many HID projectors available. Some are more ideal than others  because of price, size and whether it is a single or bixenon projector. Furthermore, there are differences in foreground, brightness, width and color flickering between these projectors, and all of which contribute to the desirability and thus the cost. Bulbs Most projectors used for retrofitting utilize D2S bulbs. The most common OEM bulbs are either made by Philips or Osram and are rated  at about 4300K, which is a white color with some traces of yellow. A higher K (Kelvin; also known as color temperature) rating does not  mean that the bulb produces more light, but rather a more blue/purple light output. In fact, 4300K produces the most amount of visible  light (lumens), while the light intensity decreases with increased Kelvin rating. In general, 6000K produces a white with some traces of  blue, while a higher K rating, i.e. 8000, 10000, 12000, etc produces more blue and eventually purple. Ballasts All HID retrofits are dependent on the ballasts, which is the part that "turns" on the HIDs. In essence it up-converts the automotive  voltage to roughly 25,000V, which excites the xenon bulbs. There are different ballasts available and they come in different prices, sizes  and with different igniter cord lengths. The igniter cord connects the ballasts to the igniter cap, which is twisted onto the back of the  projector/bulb. The length of the igniter cord can become a real significance, when too short of a cord may prevent you from installing  the ballasts in certain location. Shrouds Whether your projector is a RX330 or S2000, they all look alike on a retrofitted headlight, but what separates your retrofit from the rest is the shroud. The shrouds cover the sides of the projector, and give the retrofit the "finished" look. There are many shrouds available from OEM to custom, with the options of combining shrouds together, adding chrome trim pieces, painting, shroud extension and/or LEDs. The options to make the retrofit one of a kind are virtually endless.
