If you live in a rural area, you must be able to rely on good lighting. That's why Johan chose our new Hilox Evolution 2 xenon kit. A reliable kit that is easy to install and produces a lot of light, more than enough for the poorly lit roads in Friesland, Overijssel and Drenthe.

Seat Leon xenon kit: why did you choose for a xenon kit?
In the previous car I had already built-in xenon, but this was not in my new Seat Leon. My home-work route is in Friesland, Overijssel and Drenthe, where the roads are not well illuminated. The standard lamps had far too low light output and xenon is the perfect source of light here for safe driving.
How was the xenon kit installed?
In 1 word simple. Also because I've done it once before. But the instructions are clear and with the right tools it can not go wrong. Of course, your car must have enough space to close the lamps and to mount the ballasts neatly.
Used Products
Suitable for all Seats
Do you want such a Hilox Xenon kit in your car? That is possible, the Hilox Evolution xenon kit fits into any Seat, young, old, fat or thin. All you need is a left and a right hand (installing a xenon kit is very easy) and a xenon kit in the right fitting. Don't you know which fitting your Seat has? Then check our xenon kits or contact us.
What do you think of the end result?
Great! 6000K gives much more light output than standard H7 lamps.
Do you have any tips about buying and/or installing?
See how much space you have to mount the ballasts in your car. Take the time here and test this first, so do not immediately remove the double-sided tape. If you want LED, see how much space is available to place the cooling ribs in your headlights.
Pro Installation Tips: Install H7 xenon
In some cases, the flat Evo 2 ballast fits into the headlight as a whole. Make sure that the height adjustment is working properly. And also check the light image. With the halogen lamps draw the light/dark cutoff on the wall or garage door, this drawing must be the same after the installation of the xenon kit.
Pro Installation Tip: Adjusting the headlights
Because the headlight itself does not change anything except the lamp, you do not have to reset the headlight in most cases. But nevertheless, it's wise to see if you do not blind the oncoming traffic. Put your car with the standard lighting against a wall and draw a line along the light beam with a pencil. After installing the kit, check if this is the same.
What you should know about the H7 Evolution II xenon kit
Johan used the Hilox Evolution 2 H7 xenon kit. In the current range, that is the H7 Xenonkit, Hilox Evolution II Black, Duo. According to the product information:
- The kit contains 2 H7 xenon lamps and 2 Hilox Evolution II ballasts, with 2 years warranty on both lamps and ballasts.
- It gives 4 times more light than halogen and is available in 4300K, 5500K and 6500K. Johan chose 6000K in his Seat Leon, so check which colours are currently available.
- A small IC chip in the ballast keeps the current stable and prevents overheating and flickering lamps.
- CAN-bus II makes it possible to install the kit in cars with CAN-bus or lamp control.
Before you order
As Johan's tips show, the ballasts are the part that needs the most planning. Check where you can mount them, test the position first and only then remove the double-sided tape. In some headlights, the flat Evo 2 ballast even fits inside the headlight. Also remember that xenon needs a short warm-up time before it reaches full strength; that is normal.
Want to compare the options? See all Hilox xenon kits, separate xenon lamps or xenon ballasts.
After installation, have the light beam checked and make sure your car still meets the APK requirements. If in doubt, ask the RDW or your inspector. The Hilox product information states that this kit has no ECE approval and is intended for circuit and private terrain use only.
