The Volkswagen T5 range built on the success of the hugely popular T4 by offering over 100 different design combinations. Introducing new technology such as dual-clutch transmission, side lane assist, radio navigation and tyre pressure monitoring, this particular model, the T5 facelift, has been used as everything from trades vehicle and bus to ambulance and campervan. It remained in production 2010-2016. But the lighting technology used in these vans is over 15 years old today.
Factory-fitted options included H4, H7/H15 halogen and D3S/H7 single-xenon headlights.    
The halogen versions feature reflectors that produce an average light beam even when new. In many cases, the light output has been further compromised as bulb heat and general ageing cause the reflective layers 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 Transporter 5.2 is not recommended. But there is fortunately no need for that. Whether your car was factory-fitted with H4, H7/H15 halogen or D3S/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 Transporter 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 Transporter will look awesome with the luxurious bright light of the latest xenon technology.
