[TR] Red LEDs?

[David Massey]

That's one way to do it but for general lighting purposes (ie: where all you want is white light) it is more efficient and cost effective to use a phospher lens on a blue to convert some of the blue light to yellow resulting in what appears to be white.  Since there isn't all that much red it won't work as well behind a red lens as will a red LED.

Here is a link to how white light is made with LEDS. Flat screen TVs do the
RGB white light thing all day long.

What is important about this is that the red tail light lens blocks most of
all the light but the red light whether it is produced by incandescent,
fluorescent or LED.
A red LED bulbs output will have very little of its light blocked so you get
all the light you are paying for. On an RGB LED you might as well disconnect
the G and B parts as they contribute very little to the output.

Finally decided to switch to LED bulbs for the TR3 stop/running lights. ISTR
that LED bulbs for the rear should be red to go behind the red lenses.  

Am I correct in this thinking?
