I've had PIAA's, Eurolites, NGTecs, Litechs and Sylvania Silverstars. Out of all these the Silverstars were definately the brightest. The other bulbs are more blue and "ricey" but only lasted up to 8 months (Eurolites) and the worst were the NGTecs. They had the least amount of light plus only lasted a little under 2 months.RyanJayG said:my silvania silverstars have lasted me a year now, fogs and headlights.
and they are quite a bit cheaper than the PIAA's
