Somebody told me we have H4 lamp model and on a website I saw 9003 ?? I need that information before to place my order. thanks in advance for any answer. It will be appreciate.

 

i believe the H4 is the 9003 high/low equivalent, which is what you would need.

 

I'm looking for those bi Xenon kit with the moving lamp, this way I can enjoy the xenon light on high and low beam. But what do you mean H4 = 9003 ? They different model no ?

 

9003 is the kind of bulb..it is sometimes designated the H4 when talking about HID. the bulb doesnt physically move, it just reflects the beam in a different way when you switch to between high/low. so yes you want the 9003 bulb
