My left headlight has gone out. I've jiggled the wires a bit, flashed my lights on and off and it still hasnt turned back on. I noticed that when i turn them on the ballast on the right side will make the warming up noise but the left one doesnt. So do you guys think i gotta replace the whole set up or is their a specific problem? Help Plsssss!!!

 

Make sure that your fuse is ok, and make sure that the connections are secure

 

quick way to tell which is bad..... switch the ballasts or bulbs. and look at the bulb very closely! if the bulb has like a DIM flash to it, then it could be the bulb thats bad...
BUT thiers only 2parts that can go bad THE BULB or the BALLAST..... so easiest way to tell which has gone bad is knowing the GOOD components switch them around...
dont guess or asume... cause you could be wrong..

i had a problem with my hids before... the bulb had a dim 2 flashes when i turned them ON... i asumed OK the bulb does lite alittle so gotta be the ballast.... had oznium send me a replacement ballast... to wait about a week just to go flap it on the car.... and then have THE SAME PROBLEM!! turned out to be a bad bulb.
