led tail light !

First such comparison I've seen, and very convincing.  :clap:

Did you use red or white LEDs?  Wondering if white would be so bright as to show white through the red lens.  Is the red LED any dimmer than the white?

Thanks. I used red LEDs both times. White would not yield good results due to color temperature and filtering by the red lens. In other words, the color would be more orange-like and the light dimmer than with red LED of the same characteristics.
