Its for Hyundai i40 2010- h7 bulb holder the original part was made out of ABS witch always melted.
I suggest to use PVDF or PCCF filament, (PVDF is self extinguishing)
V2 is for ceramic insert for the bulb (the ceramic connector can be glued with Bison urethane 2component glue)
V3 is compatible with the original connector.
