Ford Mondeo mk4 Bi-xenon kit
Bi-xenon retrofit kit for the Ford Mondeo mk4 (2007–2014) that replaces the original faded bi-xenon projectors with much more powerful bi-xenon projectors, keeping the original headlight aiming and automatic levelling.
While the headlights are off
For full output the lenses must be in good shape. Yellowed or scratched lenses scatter light and blur the sharp cut-off. While you are removing the headlights anyway, it pays to replace the covers at the same time.
Even complete beginners can do it
The front lenses stay sealed. Everything is done through the bulb opening. Not counting removing and refitting the headlights, it takes one to two hours.

An electrically controlled shield gives you two beams.
The reflector focuses the bulb's light to the lens's focal point. That is where the shield sits. The lens projects a sharp cut-off onto the road.
Low beam
The shield absorbs the lower half of the rays heading into the lens. The lens flips the image so light shines only below the cut-off. The result is a sharp cut-off that rises to the right towards the roadside. As a result, oncoming drivers are not dazzled.
High beam
A solenoid folds the shield down and all the rays pass through the lens. The cut-off disappears and the light shines like the low beam, plus far ahead of the car. The original halogen high beams shine at the same time.
Why original projectors barely shine after years
Inside the original projector, a reflector has a thin chrome layer. Over the years, heat and UV from the bulb burn it off. The surface turns dull or black and light has nothing to bounce off. The bulb shines, but only a fraction of its light reaches the road.

A reflector that lasts much longer
The reflector is made from aluminum. It dissipates heat better, so the chrome lasts much longer than the original, and the reflector doesn't warp. Light bounces off the whole surface, not just what is left of it.
Geometry like modern cars
The reflector, shield and lens follow modern projector design, not the technology from when the car left the factory. More light from the bulb reaches the lens and is then projected onto the road.
Sharp cut-off, clear lens
The shield is laser-cut, so the cut-off is sharp and oncoming drivers are not dazzled. The crystal-clear lens lets through maximum light and leaves the typical blue edge.
Before you order
Only for original xenon headlights
The kit is for original Ford Mondeo mk4 xenon headlights. Have aftermarket Depo headlights? Write to us before you order.
Lenses must be in good condition
Cracked or yellowed lenses disrupt the cut-off, cause glare, and reduce output. We have new headlight covers for this car.
Road use
The kit is not intended for use on public roads.
Frequently asked questions
Did not find your answer? Write to us.
How do I know I have original xenons?
Your headlight will carry the car maker’s logo or be made by Hella, AL or ZKW. The surest way is to send us a photo of the back of the headlight. We will confirm whether the kit fits.
Can I fit it myself?
Yes. Every kit comes with a guide, and if you get stuck, we will help.
Will automatic leveling still work?
Yes. The original aiming and automatic leveling stay. Because the new projectors mount on the original fixings, the retrofit comes with no compromises.
What about high beams?
The kit also works as a high beam. You can keep the original halogen high beam connected; then both sources shine.
Can I use LED bulbs?
Yes, if they have a base.
Full kit description
Our retrofit kit for Ford Mondeo mk4 (2007 - 2014) contains everything you need to replace the original bi-xenon projectors with much more powerful ones while keeping the original headlight aiming and automatic levelling.
The main advantages of our bi-xenon projectors
- Multiply stronger light output
- A high beam source will be added, the original high beams may or may not be retained. It's up to you.
- Projectors are unlike the original made from aluminiumso that it won't warp or burn even after years. At the same time, they also help to better dissipate heat, which makes the projector chrome has a longer life than the original lights.
- The projector's aperture is laser cut to achieve the most accurate light refraction. At the same time, it does not let any light above the refraction, so it does not glare on oncoming vehicles.
- Projectors have crystal clear lenswhich is used for maximum brightness and leaves a blue coloured refraction.
This is a simple conversion that even complete beginners can handle. There is no need to unstick the front Plexiglas for the lights. Everything can be done through the hole to change the lamp and, if you ignore the dismantling and fitting of the headlights, you can expect the job to take between one and two hours.
The kit is assembled to be completely Plug & Play, which means that there is no need to modify anything for the installation. We also create for each car detailed guide, which will completely guide you through the installation, or we can help you with the installation via phone, email or social media.
The set includes two bi-xenon projectors, bulb holders, adapters, and all the necessary mounting hardware for installation.
The projector fits the original D1S xenon lamps, so there is no need to purchase new ones for the conversion. LEDs with D1S socket can also be used.
To ensure perfect brightness, the headlight lenses must be in good condition. Cracked or yellowed lenses distort the light refraction, which can cause glare for oncoming vehicles and significantly reduce brightness. In our offer, we have headlight covers for Ford Mondeo Mk4which you can find here.
The set is not intended for use on public roads.
The set is designed for OEM Xenon headlights.
