[DeTomaso] LEDs - approaching last call!

[David & Marilyn Bell]

A red tail light lense is really just a filter that removes all the light
except red wavelengths (an amber lense would be the same but just different
wavelengths).  So if you put a white light of a given intensity behind a red
lense and all the light spectra except red are absorbed, then only a small
percentage of the total light emitted by the white LED actually passes
through (as JT says it is 'diminished').  On the other hand, virtually none
of the light emitted by a red LED is absorbed by a red lense, so practically
everything emitted by a red LED passes through a red lense to your eyeball
on the other side.  It doesn't just appear brighter, it actually is
brighter.

JT,

The actual LED lamps are all white, correct?   That is, the colors that are
seen when the units are assembled on the car are solely by virtue of the
colored lenses, not the actual color of the corresponding LEDs?
