do you need two different bulbs for one light for the high and low beams. Like for example do i need a low beam bulb and a high beam bulb in one separate light? im asking this b/c i noticed that there is two halos and i kno that one bulbs goes in one of them and what is the other halo for? just for show?

 

there are 2 bulbs already in the halo/projector head lights.
the factory harness plugs right in and our fine. now for the halos and the LED stuff you have to either wire up a switch or do what i did and splice into the parking lights so thy come on with them

 

yea so is one bulb for low beams and the other is for high beams?

 

yes.
