There are two types of headlights for the VW Transporter T5.2. For the halogen H4 headlight, the Mini D2S 3.0 is the best choice with a large shroud of your choice. For the H7 headlights the Mini H1 is the best choice. As you can read in our headlight database, this headlight is sealed with butyl. Pretty easy to open :) The VW Transporter has a canbus system, so canbus ballasts are recommend for this retrofit. Even as the H4 stand alone canbus wire (in the H4 headlight) to connect it all canbus proof. In the H7 headlight, you'll need the H1 high beam splitter. plug these between the current high beam connector and the H1 high beam bulb, and taps the 12V directly to the projector (plug and play)!
