A couple of weeks? You were lucky.I got burned by those Silverstar Ultra bulbs once too, they are somewhat brighter, but they only lasted a couple of weeks. Maybe they work better in a car but they don't like motorcycles at all, probably the vibration.
Mine lasted all of 4 days. On the 5th day it went back to Walmart. I'll be damned if I'm gonna pay $25 for a bulb and it not even last a week. And yes, I even used latex gloves so no oil from my fingers woul get on the bulb...Made no difference.
