This Mitsubishi Galant Fortis came in with its factory D4S Xenon headlights. The original bulbs had aged, so the vehicle was upgraded with NaoEvo D4S LED bulbs.
The finished setup replaces the factory D4S Xenon bulbs with NaoEvo D4S LED bulbs, giving the Galant Fortis a brighter white light and a cleaner look at the front.
The Original Setup
The Galant Fortis was running its factory D4S Xenon bulbs. Xenon bulbs can lose brightness as they age. This can happen gradually, so the change may not be obvious until the headlights no longer provide the same light they once did.
For this vehicle, the decision was to replace the ageing D4S bulbs rather than leave the original setup in place.
The Upgrade
The factory bulbs were replaced with:
Factory: D4S Xenon
Upgrade: NaoEvo D4S LED bulbs
The NaoEvo D4S LED bulbs provide a whiter light than the original Xenon bulbs and give the headlights a more modern appearance.
The replacement also keeps the original D4S application, making it a direct lighting upgrade for the existing headlight setup.
Installation
The upgrade involved:
- Removing the original D4S Xenon bulbs
- Installing the NaoEvo D4S LED bulbs
- Testing the headlights after installation
- Checking the beam alignment
- Carrying out a final lighting check
Beam alignment is important after any headlight work. The aim is to keep the light where it is needed on the road without unnecessarily affecting other drivers.
How the Galant Fortis Looks After the Upgrade
The difference is easy to see when the headlights are switched on. The original Xenon light has been replaced with a whiter LED output, giving the Galant Fortis a cleaner appearance at the front. The upgraded bulbs also put more light on the road compared with the ageing factory setup.
For a vehicle that is regularly driven at night, replacing tired Xenon bulbs can make the headlights feel noticeably fresher without changing the entire headlight assembly.
Why Upgrade the D4S Xenon Bulbs?
If the factory Xenon bulbs have been in the vehicle for years, reduced brightness can become noticeable over time. Replacing them with new lighting technology is one way to update the existing headlight setup without replacing the complete housing.
For this Galant Fortis, the upgrade was straightforward:
D4S Xenon → NaoEvo D4S LED
The result is a cleaner white light and an updated appearance while keeping the vehicle's existing headlight application.
The Finished Setup
After the upgrade, the Mitsubishi Galant Fortis has:
- NaoEvo D4S LED low-beam bulbs
- Whiter LED light output
- Updated front-end appearance
- Checked and aligned headlights
- Professional installation
Upgrade Your Mitsubishi Galant Fortis
If your Galant Fortis is still using its original D4S Xenon bulbs and the light output has dropped over time, the bulbs can be replaced with NaoEvo D4S LED bulbs.
Frame Frontiers handles the installation and headlight alignment so the finished setup is ready for night driving.
