Hi

I've just bought 1 pair of h4 bi-xenon bulbs, and they have a 4 wire connector besides the AC wiress for firing up the bulb itself. I think the 4 wire connector has to do with the builtin motor which moves the bulb. Anyone knows what to connect to it ? Or what does every wire do in particular ?

Thank you

Hi. if is possible to know, where you found this bulb ? and you already solv the problem ? ( about the wiring of the actuator of the lamp...) ?
tks for your reply

There are 2 wiring without connecter is going to the battery.
And the other two are going to the starter.
