I had Silverstar 880ST'* in my 1994 SLE last summer -the right one burnt out at like 4 days old, and the left something like 3 days later.
I transplanted the SS low-beam 9006'* into my 1998 SSE and one burnt out at about 3 months and the other just burnt out I noticed when I saw the car last night.
IMO, I will never buy Silverstars again. I would rather have the cheap blue ones off e-bay. My brother has had his 9004 Xenon blues that he bought off ebay for $15 including shipping for over 5 years now and they are both still good. Much better Bang-for-the-buck.

I've got all six front bulbs from "EuroDezigns" going on two years...

sorry i have no idea anymore... but they are ricer blue... just search for blue 9006... get em for $10

I've got Cool Blues high and lows for over a year now with no problems

I'm with you on that one. My silverstars had a very short lifespan.

my silverstars are over 2 years old, i had the bulbs in my car, fi it got totalle di took em out and put em in the bonne, no problems yet, tho i dont tihnk they are bright as they would have you believe, i just dont see the need to replace them unless they burn out

ha i never really liked silverstars cuz of the price and not blue enough for me. my hyper-whites from street glow are amazing and they send you a alcohol wipe kinda like the hand wipes. cheaper, more blue, free alcohol, yah definately seems like a better choice.

So the two biggest voices in the SS failures here are both 2k+ Bonnevilles. Less vibration damping in the newer headlight mounting? Perhaps?

i dunno about that, i see my light beams get lostled alot on signs and the back of cars whenever i hit a bump, at first i thought sometihng was broken, but everything is secure so i can only assume its normal

My Aurora ate (literally ate) 5 Sliverstars over 15 months. Suffice to say, I used to pimp SS, not anymore. Cool blues now, so far so good.
