Factory Parts: If you're wanting to change the beam pattern or color on your Morimoto 4Banger LED pods or just want backup lenses for a rainy day, here's your opportunity! When focus is irrelevant and broad output is more important, enter the 4Banger Flood beam! Designed to diffuse the output of the potent Nichia or Osram chips within, the Flood lens emits a broad (but shallow) range of output. All Weather: The white-output version is ideal for all-around visibility. For those who desire optimal output in rain, snow, or fog--the Yellow-output version will slay in shady weather. Note: factory-spec yellow NCS 4Bangers also use yellow LED chips, so installing a set of replacement yellow lenses will not yield the same deep yellow color as a factory spec NCS pod.
