Hello Guy,

I hope this may answer your question- I have a US car with four headlights. The outer headlamps have ONE bulb with TWO filaments, a high beam and a low beam. Three wire plug behind the lamp. The inner headlamps each have ONE bulb with ONE filament, high beam only. There is a two wire plug behind the lamp.    Does this match what you have on your car?

Regards, Dave.
