Over the past few years you may have noticed that car with headlights that have a "blue" tinge to them seem to be appearing in many places. These lights are more energy efficient and produce a brighter beam of light.
The various headlight styles are now available with a hint of blue. With gas filled bulbs this is a new technology called High Intensity Discharge (HID), meaning some clever inventors have found a way to apply the same technology used to illuminate stadiums to car headlights. When these new headlights are produced, there is a light blue powder applied to the lenses that acts as a filter and makes the light actually brighter and whiter for the driver. For those looking at the headlights this powder makes the lights appear blue.
Because these headlights are still in the introductory phase, they are typically only standard equipment for the higher-end cars and trucks. Because these lights can be considered a status symbol or sorts, some have tried to recreate them with spray paint and sell them as knock-offs. Often a person cannot tell the fake light just by looking at it. If you are going to add some of these headlights to your vehicle as an after market modification, get them from your local auto parts store and not from Joe Bob down the street. Not doing so can cause some disastrous results.
