After months of bench testing, lighting experiments, paint trials and work around the original trunk handle garnish, Mark V. Kampen from KM-Tronics has shared the first installed prototype photos of the sedan version. The update follows the earlier 9-3NG SportCombi LED bar project, which has already moved from prototype development into a listed DIY product.
That SportCombi version proved the basic idea. The sedan prototype now shows how much of the concept had to be reconsidered for the four-door 9-3NG rear end.
The sedan does not give the same visual working space as the SportCombi. The light bar has to live inside the narrow trunk handle garnish above the license plate, not across a broad tailgate panel. That detail is important because the factory Saab 9-3NG Sedan rear design depends on the relationship between the iceblock tail lamps, the license plate recess and the silver handle trim. Any upgrade that ignores that geometry looks wrong immediately.
Mark’s latest photos show the LED strip installed inside that original garnish area, with the SAAB lettering centered and the red illumination running left and right across the handle trim. The rear position lights are also visible in the sedan’s iceblock lamps, giving a more realistic view of how the bar works alongside the factory rear lighting rather than replacing its visual role.

The sedan prototype is now ready for real testing
In his Instagram update, Mark wrote that the new prototype is finally mounted on the Saab 9-3NG Sedan and ready for testing. He added that KM-Tronics is trying “a lot of new things” on this version and would like help from owners willing to test it.
The message is important because KM-Tronics is not presenting this as a finished product. The wording remains careful: the sedan LED bar is still under development, and the team is looking for honest feedback before moving toward any possible release.
The YouTube description gives more context. KM-Tronics describes the video as a promo for the Saab 93NG Sedan LED bar and the brighter LED option for the 9-3NG Estate LED bar. The company also states that the sedan version is still under development, that it does not yet know when or if it will release the product, although it likely will at some point, and that it is looking for a few testers.
Owners interested in testing are being asked to contact KM-Tronics directly at:

Mark also notes that a NEVS 9-3NG from 2014 is acceptable, which matters for the small group of owners running the later NEVS-built cars.
Why this prototype stage matters
The earlier bench-test photos were useful because they showed the LED intensity, the SAAB lettering, the thermal testing approach and the attempt to balance brightness without overpowering the rear lights.
The installed prototype now answers a different question: does the idea work on the sedan’s actual rear architecture?
From the new photos, the concept is much easier to judge. The LED strip sits where it should, in the handle garnish above the license plate. The sedan’s lamps remain the main rear lighting units, while the LED bar adds a horizontal signature across the center. That is the correct hierarchy for this car.
The strongest image is the straight rear view of the silver sedan. It shows the LED line clearly across the garnish, with the license plate lighting below and the trunk surface still recognizable as original 9-3NG sedan architecture. The angled night shot is more dramatic, showing how the red line reflects on nearby bodywork and how the bar behaves in low light.
The first comparison photo, showing Sedan and Estate together, is useful for another reason. It confirms that KM-Tronics is now working toward a broader 9-3NG LED bar family, not a one-off SportCombi experiment.
Sedan and Estate are not the same job
The SportCombi version had a different rear layout, and the Estate LED bar could use the wagon’s tailgate proportions more naturally. The sedan version is more restrictive.
On the sedan, the light bar has to stay close to the factory handle trim. It cannot become a large replacement panel without changing the character of the rear end. The factory silver garnish is part of the car’s visual width, but it is still a handle element, not a full rear light panel.
That distinction is exactly why the installed prototype is valuable. It shows the LED bar placed where Saab owners expect the original trim to be. The update does not try to turn the 9-3 sedan into a 9-5NG imitation. It takes a later Saab lighting idea and compresses it into the smaller sedan garnish area.
That approach makes more sense for the 9-3NG. The car keeps its original rear proportions, while the red line gives the trunk area a stronger night signature.
What testers will likely help determine
KM-Tronics has not published a final specification yet, and the latest description makes clear that several things are still being evaluated. Based on the earlier development updates, the most relevant testing areas are likely to include LED brightness, heat behavior, resistance values, wiring, paint and finish behavior, weather exposure and how the light works alongside the factory rear lamps.
Brightness will be one of the most important issues. The bar has to be visible enough at dusk and at night, but not so strong that it distracts from the original tail lamps or creates glare. That is especially important because the sedan’s LED strip sits close to the license plate area and below the trunk lip.
Fitment will matter just as much. Saab owners are usually unforgiving when a part does not sit properly against original body lines. The trunk garnish area on the 9-3NG sedan is small, exposed and very easy to judge from behind. A good prototype has to look acceptable from close range, not only in a night photo.
Weather exposure is another major test. The bar sits on the rear of the car, where it will meet water, dirt, vibration, temperature swings and repeated washing. A working bench prototype is one thing. A part that survives daily driving is another.
A small update with real aftermarket significance
The Saab aftermarket now depends heavily on specialists who are willing to develop parts in small volumes. KM-Tronics has already shown that with the SportCombi LED bar, and this sedan prototype suggests the same development path may now be opening for four-door 9-3NG owners.
That does not mean the sedan LED bar is ready to buy. It is not. Mark’s own wording is careful, the product is still under development. But this is the first time the sedan version has been shown mounted on the car, illuminated, and ready for real-world feedback.
For 9-3NG Sedan owners, that is the key shift. The project has moved from “planned” to “installed prototype.”
If testing goes well, KM-Tronics could eventually have both the Estate and Sedan covered, with the Convertible still the remaining body style to watch. For now, the next useful step is owner feedback from cars that can expose the prototype to normal use, not just workshop conditions.
