Takara recall - the low-beam headlights in my Altima are dangerously dim, and I was told it had nothing to do with my bulbs. I was told by Nissan it's a wiring issue but online it states "the material inside the projector bowl wear down, burn off, or scuff up, the projector lens doesn't receive as much light to, well project".
