I own a 2002 Volvo, the one that keeps your lights on whenever the car
runs. Problem is, in 5 years all factory lights have worked till last
year when I replaced one burnt out headlamp with a SilverStar. The
Silverstar has since been replaced with yet another silverstar, and
now a regular bulb. In one year, 2 Silverstars lasted 6 months each,
with only 9000 miles of driving. I went back to regular bulbs. I did
not touch or scratch the bulb on removal or instalation, Silverstars
just cant do the hours needed.
go to www.suvlights.com and get osram or philips/narva +30 or 50. I
had silverstars in my foglights for over two years. They did not last
that long in the headlight position. I also disabled my DRL's as I
dont need the government telling me whentoturn on lights
I forget the exact numbers but "standard" lights are rated to last
around 1200 hours of use. The "high output" lights, like silverstar,
are only rated for a few hundred hours. It's the tradeoff you have
for more light. So if they are always on due to the DRL feature they
won't last long.
I believe the short life involves two factors. First I believe the
Silverstars have a shorter life by design. That is part of the tradeoff for
longer life. Second is dependent on the design of the headlamps. If they
don't provide much air circulation (cooling) the hotter running Silverstars
will be more likely to suffer than standard lamps.
