I have Silverstars in my NB.
They are 55W as the original equipment and are DOT approved.
Yes, the light is stronger and much whiter, without that cheap stupid "blue"
look.
First set went after 8 months (within 2 days) and I do not have day running
lights.
At $20 a piece, this make ca $60 a year. Not cheap.

Regards,
Kempi
