i just bought them on ebay got 4 glass housings and 4 h4 bulbs, the h4 bulbs they gave me are those blueish ones, i hear there not so good. anyways all 4 bulbs look like they can run high and low beams - is this normal can i buy h4s for just the high beams an just low or should i use just them anyways? im not sure if the low beams stay on when the highs are on.

also can anyone point me in the right direction for wiring the bulbs, i just plugged them in and all my lights were on wether i had the highs or lows on.

i know here alot im asking of but you guys are the most knowledgeable when it comes to this stuff.

thanks,
