The Touareg, developed through a joint venture by the Volkswagen Group, Audi and Porsche, is built on the same platform as the Audi Q7 and Porsche Cayenne. Marketed as the most capable off-road vehicle of all, the predecessor to this particular model was made to tow a Boeing 747 to prove the point. This, the first Toureg facelift model, built on that reputation with major upgrades, including some 2,300 redesigned parts. New features included ABS Plus brakes, adaptive cruise control and blind-spot monitoring. With the Touareg Mk1 facelift remaining in production 2007-2010, the lighting technology used in these cars is however over 15 years old today.    
Factory-fitted options included H7/H9 halogen and D1S/H7 bi-xenon headlights 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 bi-xenon setup features a 3.0-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 Touareg Facelift is not recommended. But there is fortunately no need for that. Whether your car was factory-fitted with H7/H9 halogen and D1S, D1S/H7 bi-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 Touareg 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 Touareg will look awesome with the luxurious bright light of the latest xenon technology.
