The cheap LED's I had in my reverse lights started flickering and dying after a good 5+ years. I found even with my backup camera, it was still pretty hard to see when backing up in the dark. Saw these Auxito bulbs on sale on Amazon, and having good experiences with other Auxito bulbs I decided to give them a try. HOLY S$%#@. It's like having rear headlights! Appears they have some sort of projector housing built in. The light pattern is perfect, they really illuminate the ground and peripherals, and they are bright enough my backup camera operates like it's daylight.
