just my $.02...i had silverstars a while ago and they lasted about 2 months...never used PIAA but i believe they come with a 1 year warranty. honestly, you should look into HIDs, if you look on ebay for as a seller, you can find HIDs w/a 3 year warranty and they're only about $130 including shipping. they've lasted me about 2 months now and no problems and i've heard of many people using these same lights with no problems...
