Ford Crown Victoria Headlights

Headlights let you drive at night and during other low visibility conditions. They also allow other drivers to see and communicate with you. Here are some questions and answers about headlights, a vital safety component of your vehicle.

This depends on the type of headlight assembly you have. Composite headlights consist of lenses and reflectors. They also contain bulbs you can remove and replace when necessary without having to replace the lenses and reflectors. Sealed beam headlights contain lenses, reflectors, and filaments in one piece. Although sealed beam headlights do not allow you to remove and replace just the bulb, they are airtight and watertight.

New bulb types appear intermittently, but a few long-standing examples include:

• Halogen: These contain a tungsten filament surrounded by a halogen gas. The tungsten emits illumination when electricity courses through it. The halogen gas prolongs the tungstens life and prevents darkening of the bulb.
• LED: These are bulbs in which electrons recombine with electron holes and yield photons after electricity interacts with a two-lead semiconductor.
• Xenon: These are xenon gas-filled bulbs in which electricity leaps between two tungsten electrodes.
• HID: Short for High-Intensity Discharge, HID works just like xenon bulbs, except their internal electrodes are closer together. The gas inside the bulb may be xenon or mercury vapor.

Ford Crown Victoria projector headlights boast elliptical housing and a concave lens. The resulting illumination travels in a uniform direction rather like a film projector. Brightness levels and directionality arent better or worse; theyre just different. Projector headlights provide focused illumination and reduced scatter whereas traditional headlights offer comprehensive brightness over a wide swath of space from left to right.

The figure 6000K refers to color temperature. The letter "K" denotes Kelvin, a unit of thermodynamic temperature. Different types of bulbs emit heat energy corresponding to a particular degree of Kelvin. When a specific bulb reaches its maximum heat energy, the bulb takes on a unique color. The color changes as the temperature rises or drops. Color temperature describes this palette according to how hot a given light burns. The following is a concise breakdown.

• 2000K to 3000K: Reddish-yellow light
• 3200K: Yellow light
• 4500K to 5500K: Pure, bright white illumination
• 6000K to 7000K: Bright gray-to-crystal-white light
• 7500K to 12000K: Blue and dark blue
