Do 'environmentally friendly' LED lights cause BLINDNESS

41. Incandescent lights in automobiles are very inefficient.

The filament runs cooler than a household light bulb, emitting more red and infrared, and less "soft" white. They are designed this way so they hold up better to constant vibration. A surprising amount of energy is also lost in the car's wiring, pushing incandescent lights even further toward the red side of the spectrum. Since LEDs are more efficient they can be brighter and draw less current.

Another factor is the way our eyes respond to color. Scurrying around in the dark, our mammal ancestors managed to lose two of the excellent color receptors of their reptilian ancestors. Our great ape color vision is a kludge, a single color receptor was duplicated and modified very slightly allowing us to distinguish red from green.

There is considerable overlap in the sensitivity of the red and green receptors so a further kludge very much improved our ability to distinguish red from green (useful for finding ripe fruit) at the expense true trichromacy. This kludge made the red and green signals antagonistic to one another in processing. If there is any green leaking through the red tail or brake light lens, as there is with an incandescent bulb, then the red color seems much less intense than it does with a pure red LED that doesn't produce any green light.
