I've been having this problem too. My passenger side low beam is also noticeably dimmer than the driver's side. After inspecting the connector i noticed that all of the terminals were burnt up. Now i've gotta find a connector somewhere, and i've got the same problem the westerboyz has with the broken clip.
I am LOVING the Apexcone setup. You've got a PM coming your way about them
ur lucky
ive replaced all 4 of my front bulbs at least once in 2 years
i think the drivers side low beam 3 times!
