H11 HID Headlight Conversion Kit

Directly replaces your stock Halogens with Xenon bulbs

If you are the one who is looking for the car bulbs that will illuminate every road on your way and each turn, this H11 headlight kit is what you need! The newest technologies were combined to give a real brightness to your headlights.

These HID lights have metal base of the H11 size which is designed to lock the bulb in the housing securely. The rubber washer prevents moisture and dirt from getting into the headlight assembly. This H11 headlight and fog light kit has waterproof connections which make this bulb set water resistible.

A quartz glass is used for manufacturing of the HID Xenon light bulbs. This material is resistible to high temperatures and vibrations. That is why it helps prolong the lifespan of the H11 headlight bulbs.

This premium conversion kit comes with a pair of AC Xenon ballasts. They are power units which are needed to ignite the Xenon light bulbs. The ballasts have shockproof, waterproof and slim design. They can be easily mounted in the engine bay with a help of a set of brackets and screws that come with the kit.

Usually, the installation takes from 20-50 minutes. It depends on your vehicle and the headlight assembly specification.

You can choose one of 12 available color options to upgrade the visibility and look of your vehicle. The most popular colors which give the maximum light output are 4300-6000K. These tints are close to the daylight and pleasant for a human eye.

Our H11 conversion kit is perfect choice for those who are looking for an option to upgrade low beams or fog lights. Purchasing these bulbs, you get a full setup to replace the headlight bulbs.

Some vehicles may require installation of additional accessories to make the aftermarket kit work properly.


  • Two 35W H11 bulbs
  • Two high-performance slim digital ballasts
  • Two mounting brackets
  • One smart aluminum carry-case
  • One installation manual

Note that H11 bulb is L-shaped only.

Highly recommended to add a universal single beam relay harness that provides safety, prolongs lifespan of all the parts of HID system and shuts off most of the issues related to headlights operation.
