How to Change Your Impala to HID


High intensity discharge, or HID, provide bright light and a stylish look to your Chevrolet Impala while using far less power than a traditional halogen lamp. Installing an HID kit is similar to changing the original headlight bulb, with the exception of a few extra components. Most HID kits come with all needed wiring, hardware and lights needed, and most plug into the factory wiring harness of the vehicle.

Things You'll Need

  • HID conversion kit
  • Socket and ratchet set
  • Double-sided tape
  • Disconnect the negative battery cable with the socket and ratchet set. If you cannot easily access the factory headlight bulbs, remove the two bolts securing the bulb housing to the vehicle with the socket and ratchet set.

  • Disconnect the wire harness from both bulbs you intend to convert to HID. Turn the factory bulb clockwise and remove it from the headlight fixture.

  • Connect the HID wire harness to the vehicle's factory headlight wire harness for each side of the vehicle. Each plug should slide together and click into place.

  • Place the new xenon bulbs included in the HID kit into the housing and turn counterclockwise to lock into place. Locate a flat spot within reach of the bulb housing on both sides and attach the ballast with the double-sided tape. Be sure the ballast is close enough for the wires to reach the new bulb.

  • Plug the wire harness from each ballast into their respective bulbs. Mount the headlight housing back into place and tighten the bolts using the socket and ratchet set. Connect the negative battery cable with the socket and ratchet set.

Tips & Warnings

  • HID lights are generally only used for low beam applications.
  • A separate kit must be ordered for high beam applications.
  • Always disconnect the battery from the vehicle to prevent the risk of electrical shock.
