Dome Lights are acting weird, Any idea of how to fix this/make them work properly? Options

[Valo666]

So, for some odd reason, one of the two dome lights lights up dimmer then the other. I used the same bulbs, same package and every thing. This is the weirder thing though, it only happens once in awhile, and its only the light near the steering wheel thats not bright. Any one know if there is a brighter bulb out there?/any companies make aftermarket bulbs for the dome light? I kinda want to b able 2 use them. I seriously cant see any thing in my car at night.
