Vendor: Kensun


HID Conversion Kit

Single beam headlights set directly replaces your stock H4 Halogens with Xenon Bulbs

If you're set on using HIDs in your car, you can use a 55W HID H4 Conversion Kit, which allows you to convert your halogen headlights to Xenon. We are glad to present you with our bulbs that add your car a brighter look, and make the driving feel differently, in a good way.

What makes Kensun light bulbs be of such high demand?

The first and most obvious reason is brightness. Because of their outstanding illumination, they provide you with better and further visibility during night-time driving.

What are the color options?

Xenon bulbs can also produce higher color temperatures than halogen. This means that you can achieve a very strong regular ice white/blue light on the road with a Xenon bulb. Even more so, with Kensun you are free to choose between 12 different tints to your liking. The colors vary from yellow (3000K) to indigo (30000K). The most popular among our customers are as follows: 4300K, 5000K and 6000K.

What is beneficial about Kensun lights?

The last but not the least is their longevity. Our bulbs operate on AC current which Xenon ballasts provide. These small power units are designed to provide a power supply to the HIDs and convert direct current from your vehicle into alternating. That is why our Xenon bulbs last much longer than halogen, which means that you don't have to worry about replacing them as often. This has the potential to save you money in the long run.

You are getting the headlights that are:

  • 3x brighter than Halogen bulbs
  • Lasts 5-10x longer
  • 35% less power consumption
  • TESTED: 100% Dustproof and 100% Shockproof


  • Two 55W H4 super bright Xenon bulbs
  • Two 55W high-performance slim digital ballasts
  • Two mounting brackets
  • One smart aluminum carry-case

Highly recommended to add a 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.

Due to aftermarket HIDs installation some vehicles may undergo flickering or dashboard errors issues, however it can be easily resolved by adding load resistors.
