hey there only one headlight works so i though time to change the bulb but when i put my high-beams on all the lights work take them off only the passenger side headlight stays on what could this be?????

 

the low beams are dual action bulb. they work for low and high and the inner 2 bulbs are high beam only. so in your case, you have a low beam bulb out that still has the operating high beam. there are 2 filaments in low beam bulbs wich makes them work that way.

 

hahaha ya i figured that out yesterday thanks though also where did you get your air intake cant find them like that here
