One center LED doesn't work well

Looks great, easy installation. Unfortunately, one of the center lights doesn't light up as bright as the other side. I tried wiggling wires, rotating the base 180 degrees before inserting (only goes in one way, so that didn't work), looking at soldering points to make sure everything is good. Everything seems to be in good working order, until I turn the ignition on and one light just barely lights up, while the other one shines brightly. The amber LEDs work great, very bright, and the smoked lenses are awesome, just can't get over the fact that the center white LED doesn't shine as bright.
