This Kit replaces H4656/H4651/H4652 Low and High Beam Headlights measuring:   6.50" Wide x 4.00" Tall



The XP4556 Headlight Kit includes the following components for easy installation:

  • 2 Projector HID Low Beam light assemblies, 2 LED High Beam light assemblies (1000 lumens, 1.41 Amps), 2 control ballasts, 2 HID light sources with ignitors, all wiring, wiring diagram and mounting instructions for the HID light sources.  Unlike 'retrofit' or 'adapter' packages that replace some elements of an existing headlamp system, the HID Headlight Kit includes all components except for headlight mounting brackets that are installed on the vehicle.


  • High Intensity Discharge (HID) is a type of lighting technology that replaces the filament of the light bulb with a capsule of gas. Xenon is the most common gas used in automotive HID systems. When high voltage is applied, the Xenon gas is ignited to produce an arc of light. The amount of light produced is greater than a standard halogen bulb while consuming less power and more closely approximating the color temperature of natural daylight. On the road, Xenon HID headlights appear as a bright white with a light blue tint.


  • HID lighting has several advantages over conventional lighting systems:  

o    300% more light output with approximately 50% lower power consumption (3.3A vs. 5.5A). A 35 Watt HID light source produces up to 3x's the lumens at the light source when compared to a 55 Watt halogen bulb (3200 Lumens vs. 700 Lumens).

o    Whiter light. The color temperature of HID lighting more closely approximates the color temperature of natural daylight than does a halogen system, which appears yellowish.


  • In some circumstances, minor modifications to the headlight holder or "bucket" may be required to accommodate the ballast cable.  It may be necessary to enlarge a hole, allowing the HID housing, bulb cable connector and wiring to pass through the rear exterior of the headlamp compartment. The ballast cable is 12" in length to facilitate mounting the ballast in a dry location. A separate wiring harness is supplied as the existing vehicle wiring is not designed to support the initial 30 second start-up current required for an HID ballast.


  • What if I have alternating flashers (wig wags) on my headlights?   This kit includes specially designed halogen high beam headlights that can be utilized with high beam alternating flashers.  The low beam Xenon headlights cannot be flashed for wig wags.



  • This kit includes specially designed LED high beams to maximize the performance of the Xenon HID low beam lamps.  1000Lumens at 1.41 Amps.
