n e body kno wut would cause this, I have stock wattage catz chrome blue bulbs, n da other day my left one went out, replaced it wit a catz aqua white, stock wattage n it blew out only 1 month later, is it a problem wit my wires, bulbs, or wut???

 

are you touching the bulbs when you put them in?

 

Your best bet is to get HID lights. I went to 2 sets of after markets bulbs and they both went out on me within 3 months
