FAQ
Q: Why does this connector use high-temperature PA66 instead of ceramic?
A: The DJD031A-1 uses high-temperature PA66 rated to 150°C, which is sufficient for modern H4 halogen bulbs (55W/60W) used in Audi and VW headlights. Ceramic is only required for older high-wattage bulbs or extreme heat applications (VW Santana 2000 style).
Q: Is this connector compatible with H4 LED conversion bulbs?
A: Yes. H4 LED conversion bulbs generate significantly less heat than halogen bulbs, so the 150°C PA66 housing provides ample safety margin for LED use.
Q: What is the difference between DJD031A-1 and H4-2B?
A: DJD031A-1 is a high-temperature PA66 H4 socket for modern Audi/VW headlights (150°C). H4-2B is a ceramic right-angle socket for classic VW Santana 2000 headlights (300°C). They are not interchangeable.
