Volkswagen Passat B5 facelift, also known as Passat B5.5, was built on the same platform as the Audi A4 and used higher quality interior trims to move the model further upmarket. This combined with the trademark practical qualities of the Passat range to result in an incredible popular car that won Volkswagen several awards, including Best Family Car (Auto Express New Car Honours) and Best Fleet Car (Fleet World Honours) in 2000 and Best Family Used Car (Auto Express Car Honours) in 2001. With the Passat B5 facelift in production 2001-2005, the lighting technology used in these cars is however over 15 years old today.
Factory-fitted options included H7 halogen and D2S/H7 single-xenon headlights, both made by Hella. 
The halogen version features an H7 reflector that produces an average light beam even when new. In many cases, its light output has been further compromised as bulb heat and general ageing cause the reflective layer to peel off.   
The single-xenon setup features a 2.5-inch projector, designed in the late 90s. These projectors are known to lose their reflective layer right to the point where they become black inside, causing dangerously low light output.
Needless to say, buying new or used original headlights for your Volkswagen Passat B5.5 is not recommended. But there is fortunately no need for that. Whether your car was factory-fitted with H7 halogen or D2S/H7 single-xenon headlights, there are upgrade kits that will fit inside your existing headlights.
These complete retrofit kits not only provide you with superior brightness and durability; they are also more affordable than average Volkswagen Passat xenon headlights with bulbs and ballasts, and since all components are brand new, they come with a 2-year warranty. Additional benefits over OEM headlights include Canbus-proof designs and effortless halogen-to-xenon conversions. What’s more, the levelling systems will work without any adjustments to the headlight connectors, and you can use any ballasts that you might already own to save further on xenon upgrades.
No matter which retrofit upgrade kit you pick, you will improve the light output considerably, making for safer and more enjoyable driving. And, of course, your Volkswagen Passat will look awesome with the luxurious bright light of the latest xenon technology.
