Many custom car enthusiasts may be wondering what the big deal with projector head lighting is. Visibility during the night is an extremely important safety factor when purchasing a vehicle especially considering more accidents happen during the evening hours. Many of these custom looking factory projectors are found on luxury vehicles in today’s market.

Unlike traditional dual filament bulbs, most factory projector headlights use a cutoff shield to limit light for your vehicle’s low beam output and mechanically move the shield allowing more light to pass through for the high beams. This setup is very common if you purchased your vehicle with the projector system installed from the manufacturer, this allows for a cost effective bulb replacement, as there are only single filament bulbs that utilize the mechanical shutter.

This is not the case with aftermarket; most of the custom projector systems on the market today include a dual filament bulb or High Intensity Discharge Conversion Kit that has a high and low beam, minimizing the mechanical parts in these lights. This design makes it more cost effective to build and limits the overall maintenance that the owner will need to do to keep them running efficiently.
