Review on Philips 1156LLB2 LongerLife Mini Bulb by Jeff Swan

Worked great for a while then I started getting brake light errors and bulbs went out intermittently, usually within minutes of launch. After removing the failed lamp, the inner filament support post melted on one side, causing intermittent failures. First one failed after 6 months, then gradually the others started to fail. For a supposedly durable brake light, the lifespan is terrible and I wouldn't buy it again. I ordered 3 sets of 3 and more than half didn't work. At the moment I'm replacing them all pre-emptively as I see signs of the same failure in the others. maybe i have a bad batch but from now on i avoid philips bulbs and use sylvania/osram or hella instead.
